Paul Bolle 95369a73a9 eeepc-laptop: simplify parse_arg()
parse_arg() has three possible return values:
    -EINVAL if sscanf(), in short, fails;
    zero if "count" is zero; and
    "count" in all other cases

But "count" will never be zero. See, parse_arg() is called by the
various store functions. And the callchain of these functions starts
with sysfs_kf_write(). And that function checks for a zero "count". So
we can stop checking for a zero "count", drop the "count" argument
entirely, and transform parse_arg() into a function that returns zero on
success or a negative error. That, in turn, allows to make those store
functions just return "count" on success. The net effect is that the
code becomes a bit easier to understand.

A nice side effect is that this GCC warning is silenced too:
    drivers/platform/x86/eeepc-laptop.c: In function ‘store_sys_acpi’:
    drivers/platform/x86/eeepc-laptop.c:279:10: warning: ‘value’ may be used uninitialized in this function [-Wmaybe-uninitialized]
      int rv, value;

Which is, of course, the reason to have a look at parse_arg().

Peter Ujfalusi a3d3c53f73 intel-rst: Clean up ACPI add function
There is no need to initialize the error since it is going to be assigned
with the return status of at least on of the device_create_file() call.

We can return directly in case the first file creation fails.
All the labels for goto can be removed (along with the gotos) as well.
Tell the compiler that the failures are unlikely so it can create better
binaries.

Azael Avalos 93f8c16d63 toshiba_acpi: Support new keyboard backlight type
Newer Toshiba models now come with a new (and different) keyboard
backlight implementation with three modes of operation: TIMER,
ON and OFF, and the LED is now controlled internally by the firmware.

This patch adds support for that type of backlight, changing the
existing code to accomodate the new implementation.

The timeout value range is now 1-60 seconds, and the accepted
modes are now: 1 (FN-Z), 2 (AUTO or TIMER), 8 (ON) and 10 (OFF),
this adds two new entries kbd_type and available_kbd_modes,
the first shows the keyboard type and the latter shows the
supported modes depending on the keyboard type.

Zhang Rui 4990141496 ACPI / PNP: remove Fujitsu device IDs from ACPI PNP ID list
Fujitsu backlight and hotkey devices have ACPI drivers.

The PNP MODULE_DEVICE_TABLE in fujitsu-laptop driver is just used as an
indicator for module autoloading, but this is wrong because what we
need is ACPI module device table instead, because the driver is probing
ACPI devices.

Thus remove those IDs from ACPI PNP scan handler list as we don't
have a PNP driver for them, and convert the fujitsu-laptop PNP
MODULE_DEVICE_TABLE to ACPI MODULE_DEVICE_TABLE.

Dan Carpenter aeaac098bd toshiba_acpi: fix and cleanup toshiba_kbd_bl_mode_store()
The current code just returns -EINVAL because mode can't be equal to
both 1 and 2.

Also this function is messy so I have cleaned it up:
1) Remove initializers like "int time = -1".  Initializing variables to
   garbage values turns off GCC's uninitialized variable warnings so it
   can lead to bugs.
2) Use kstrtoint() instead of sscanf().
3) Use SCI_KBD_MODE_FNZ and SCI_KBD_MODE_AUTO instead of magic numbers 1
   and 2.
4) Don't check for "mode == -1" because that can't happen.
5) Preserve the error code from toshiba_kbd_illum_status_set().

Hans de Goede 3b264d279e Revert "ideapad-laptop: Disable touchpad interface on Yoga models"
I've received a bug report from a user that the touchpad control part
of the ideapad-laptop ACPI interface does work for him on his
"Lenovo Yoga 2 13", and that this patch causes a regression for him.

Since it did not work for me when I had a "Lenovo Yoga 2 11" in my own
hands (loaned from a friend). It seems that this is a bit of hit and miss.

Since the result of having a false positive here is worse, then the minor
annoyance of a false touchpad disabled messages being shown after suspend /
resume on models (or is it firmware versions?) where the interface does not
work, simply revert the patch.

This reverts commit f79a901331.

written to ignore -ENODEV, to avoid not registering a backlight interface for
models which have no bl_power control, but do have brightness control.

At the same time the error handling for brightness_max was modified to do the
same, this is wrong, when there is no brightness_max asus-wmi should not
register a backlight interface.

Note the caller of asus_wmi_backlight_init already special cases -ENODEV,
and will not cause the wmi driver regristration to fail because of a
-ENODEV return from asus_wmi_backlight_init.

Hans de Goede ce363c2bcb ideapad-laptop: Change Lenovo Yoga 2 series rfkill handling
It seems that the same problems which lead to adding an rfkill blacklist and
putting the Lenovo Yoga 2 11 on it are also present on the Lenovo Yoga 2 13
and Lenovo Yoga 2 Pro too:
https://bugzilla.redhat.com/show_bug.cgi?id=1021036
https://forums.lenovo.com/t5/Linux-Discussion/Yoga-2-13-not-Pro-Linux-Warning/m-p/1517612

Testing has shown that the firmware rfkill settings are persistent over
reboots. So blacklisting the driver is not good enough, if the wifi is blocked
at the firmware level the wifi needs to be explictly unblocked through the
ideapad-laptop interface.

And at least on the Lenovo Yoga 2 13 the VPCCMD_RF register which on devices
with hardware kill switch reports the hardware switch state, needs to be
explictly set to 1 (radio enabled / not blocked).

So this patch does 3 things to get proper rfkill handling on these models:

1) Instead of blacklisting the rfkill functionality, which means that people
with a firmware blocked wifi get stuck in that situation, ignore the value
reported by the not present hardware rfkill switch, as this is what is causing
ideapad-laptop to wrongly report all radios as hardware blocks. But do register
the rfkill interfaces so that the user can soft [un]block them.

2) On models without a hardware rfkill switch, explictly set VPCCMD_RF to 1

3) Drop the " 11" postfix from the dmi match string, as the entire Yoga 2
series is affected.

Hans de Goede 4beb81d12d thinkpad_acpi: Update mapping for F12 hotkey on *40 models to KEY_FILE
The new keyboard found on the *40 models is also being sold as a standalone

http://shop.lenovo.com/us/en/itemdetails/0B47189/460/60AC6A0372B14F5BA7B12F1FF88E33C7

This uses a standard HUT code for the F12 key with the 6 square boxes on it,
which gets mapped to KEY_FILE by the kernel. Change the mapping done of
identical laptop key done by thinkpad_acpi to also send KEY_FILE for

Nick Dyer 50a77c658b Input: atmel_mxt_ts - download device config using firmware loader
The existing implementation which encodes the configuration as a binary
blob in platform data is unsatisfactory since it requires a kernel
recompile for the configuration to be changed, and it doesn't deal well
with firmware changes that move values around on the chip.

Atmel define an ASCII format for the configuration which can be exported
from their tools. This patch implements a parser for that format which
loads the configuration via the firmware loader and sends it to the MXT
chip.

Benson Leung 5502486a20 platform/chrome: chromeos_laptop - Add a limit for deferred retries
Limit the number of times we allow deferred probing to attempt to add
i2c devices. This will help with some device flakiness at probe time.
For example, some touchpads and touchscreens may be in transition between
bootloader and operational mode and may appear at neither address briefly.

Adapters, however, have no limit as it depends on when the i2c adapter driver
module is loaded. The module may even be loaded manually by the user using
modprobe or insmod.

By default, set MAX_I2C_DEVICE_DEFERALS to 5.

Olof Johansson d1c1437062 platform/chrome: pstore: fix dmi table to match all chrome systems
Turns out that DMI_SYSTEM_VENDOR is actually the native vendor of each
Chromebook/box. I tested the original patch on a Pixel that -- surprise,
has Google as vendor. *facepalm*.

The only other data I can think of to probe on is Google_* in the version
string.  Checking with our firmware team, all systems should have this
and nothing else than Chrome hardware should have the coreboot + Google_*
combination to date.

So, we'll switch to this. For future platforms we are going to move to
using an ACPI device to configure this instead of a DMI table (yay!),
so longer-term that will sort itself out.

We've observed the missing pvpanic call at panic, and it turned out
that this was blocked by the broken notifier of drm_fb_helper, where
scheduling may be called during switching to the fb console.
It's fairly difficult to fix the drm_fb problem and a quick fix isn't
foreseen, a simpler solution for the missing pvpanic call would be
just to call this earlier.

In order to assure that, this patch sets a higher priority to pvpanic

Merge tag 'pm+acpi-3.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm into next

Pull ACPI and power management updates from Rafael Wysocki:
 "ACPICA is the leader this time (63 commits), followed by cpufreq (28
  commits), devfreq (15 commits), system suspend/hibernation (12
  commits), ACPI video and ACPI device enumeration (10 commits each).

  We have no major new features this time, but there are a few
  significant changes of how things work.  The most visible one will
  probably be that we are now going to create platform devices rather
  than PNP devices by default for ACPI device objects with _HID.  That
  was long overdue and will be really necessary to be able to use the
  same drivers for the same hardware blocks on ACPI and DT-based systems
  going forward.  We're not expecting fallout from this one (as usual),
  but it's something to watch nevertheless.

  The second change having a chance to be visible is that ACPI video
  will now default to using native backlight rather than the ACPI
  backlight interface which should generally help systems with broken
  Win8 BIOSes.  We're hoping that all problems with the native backlight
  handling that we had previously have been addressed and we are in a
  good enough shape to flip the default, but this change should be easy
  enough to revert if need be.

  In addition to that, the system suspend core has a new mechanism to
  allow runtime-suspended devices to stay suspended throughout system
  suspend/resume transitions if some extra conditions are met
  (generally, they are related to coordination within device hierarchy).
  However, enabling this feature requires cooperation from the bus type
  layer and for now it has only been implemented for the ACPI PM domain
  (used by ACPI-enumerated platform devices mostly today).

  Also, the acpidump utility that was previously shipped as a separate
  tool will now be provided by the upstream ACPICA along with the rest
  of ACPICA code, which will allow it to be more up to date and better
  supported, and we have one new cpuidle driver (ARM clps711x).

  The rest is improvements related to certain specific use cases,
  cleanups and fixes all over the place.

  Specifics:

   - ACPICA update to upstream version 20140424.  That includes a number
     of fixes and improvements related to things like GPE handling,
     table loading, headers, memory mapping and unmapping, DSDT/SSDT
     overriding, and the Unload() operator.  The acpidump utility from

     machines and using native backlight by default.

   - ACPI device enumeration changes to create platform devices rather
     than PNP devices for ACPI device objects with _HID by default.  PNP
     devices will still be created for the ACPI device object with
     device IDs corresponding to real PNP devices, so that change should
     not break things left and right, and we're expecting to see more
     and more ACPI-enumerated platform devices in the future.  From
     Zhang Rui and Rafael J Wysocki.

   - Updates for the ACPI LPSS (Low-Power Subsystem) driver allowing it
     to handle system suspend/resume on Asus T100 correctly.  From

Hans de Goede d13374154e acer-wmi: Switch to acpi_video_unregister_backlight
Switch from acpi_video_unregister(), to acpi_video_unregister_backlight(),
so that the hotkeys handler registered by acpi-video stays in place.

Since there are no mappings for the atkbd raw codes for the brightness
keys used by newer Acer models in /lib/udev/hwdb.d/60-keyboard.hwdb, and
since we map the wmi events with a code of KE_IGNORE, we rely on acpi-video
to do the hotkey handling for us.

For laptops such as the Acer Aspire 5750 which uses intel gfx this works
despite us calling acpi_video_unregister() because the following happens:

 1) acpi-video module gets loaded (as it is a dependency of acer-wmi and i915)
 2) acpi-video does NOT call acpi_video_register()
 3) acer-wmi loads (assume it loads before i915), calls
    acpi_video_dmi_promote_vendor(); which sets
    ACPI_VIDEO_BACKLIGHT_DMI_VENDOR
 4) calls acpi_video_unregister -> not registered, nop
 5) i915 loads, calls acpi_video_register
 6) acpi_video_register registers the acpi_notifier for the hotkeys,
    does NOT register a backlight device because of
    ACPI_VIDEO_BACKLIGHT_DMI_VENDOR

But on the Acer Aspire 5750G, which uses nvidia graphics the following happens:
 1) acpi-video module gets loaded (as it is a dependency of acer-wmi)
 2) acpi-video calls acpi_video_register()
 3) acpi_video_register registers the acpi_notifier for the hotkeys,
    and a backlight device
 4) acer-wmi loads, calls acpi_video_dmi_promote_vendor()
 5) calls acpi_video_unregister, this unregisters BOTH the acpi_notifier for
    the hotkeys AND the backlight device

And we end up without any handler for the brightness hotkeys. This patch fixes
this by switching over to acpi_video_unregister_backlight() which keeps the
hotkey handler in place.

Nick Dyer fb5e4c3ee1 Input: atmel_mxt_ts - improve T19 GPIO keys handling
* The mapping of the GPIO numbers into the T19 status byte varies between
   different maXTouch chips. Some have up to 7 GPIOs. Allowing a keycode array
   of up to 8 items is simpler and more generic. So replace #define with
   configurable number of keys which also allows the removal of is_tp.
 * Rename platform data parameters to include "t19" to prevent confusion with
   T15 key array.
 * Probe aborts early on when pdata is NULL, so no need to check.
 * Move "int i" to beginning of function (mixed declarations and code)
 * Use API calls rather than __set_bit()
 * Remove unused dev variable.

Nick Dyer 2cefdb1f0a Input: atmel_mxt_ts - remove unnecessary platform data
It is not necessary to download these values to the maXTouch chip on every
probe, since they are stored in NVRAM. It makes life difficult when tuning
the device to keep them in sync with the config array/file, and requires a
new kernel build for minor tweaks.

These parameters only represent a tiny subset of the available
configuration options, tracking all of these options in platform data would
be a endless task. In addition, different versions of maXTouch chips may
have these values in different places or may not even have them at all.

Having these values also makes life more complex for device tree and other
platforms where having to define a static configuration isn't helpful.

The only real change is passing in event_mask to the formerly nested functions.
Otherwise it's just moving around function and macro code.

This is the only place in the Linux kernel where nested functions are still in
use. Nested functions aren't part of the C standards, and complicate the
generated code. Although the Linux Kernel has never set out to be entirely C
standard compliant, it is increasingly compliant to the standard which is
supported by other compilers such as Clang. The LLVMLinux project is working on
being able to compile the Linux kernel with Clang. The use of nested functions
blocks this effort.

Stefan Seyfried 58c688657c Fix sleep / suspend keys for Toughbook CF-51
Hi all,

my panasonic cf-51 does no longer react to the suspend and hibernate
keys. I cannot tell when this started since I no longer use the machine
on a daily basis, but I suspect it started when userspace switched from
using /proc/acpi/event to the input layer, wich was quite some time ago ;-)

Today I investigated the issue and found that the firmware simply does
not generate any event on "key down" for those keys, but only on "key up".

The attached patch works around the problem.

Best regards,

	Stefan

Subject: [PATCH] panasonic-laptop: fix sleep keys on CF-51

At least on my CF-51, both sleep and hibernate keys do not
generate "key down" events, only "key up". Because of this,
the input layer does ignore both keys. The work around is
to generate a key down event before the key up. To avoid
double events on non-broken firmware, this is only done if
no key down is ever seen for those keys.

Linus Torvalds c70929147a sound updates for 3.15-rc1
There have been lots of changes in ALSA core, HD-audio and ASoC, also
 most of PCI drivers touched by conversions of printks.  All these
 resulted in a high volume and wide ranged patch sets in this release.
 Many changes are fairly trivial, but also lots of nice cleanups and
 refactors.  There are a few new drivers, most notably, the Intel
 Haswell and Baytrail ASoC driver.
 
 Core changes:
 - A bit modernization; embed the device struct into snd_card struct,
   so that it may be referred from the beginning.  A new snd_card_new()
   function is introduced for that, and all drivers have been
   converted.
 
 - Simplification in the device management code in ALSA core;
   now managed by a simple priority list instead
 
 - Converted many kernel messages to use the standard dev_err() & co;
   this would be the pretty visible difference, especially for
   HD-audio.
 
 HD-audio:
 - Conexant codecs use the auto-parser as default now;
   the old static code still remains in case of regressions.
   Some old quirks have been rewritten with the fixups for auto-parser.
 
 - C-Media codecs also use the auto-parser as default now, too.
 
 - A device struct is assigned to each HD-audio codec, and the formerly
   hwdep attributes are accessible over the codec sysfs, too.
   hwdep attributes still remain for compatibility.
 
 - Split the PCI-specific stuff for HD-audio controller into a separate
   module, ane make a helper module for the generic controller driver.
   This is a preliminary change for supporting Tegra HDMI controller in
   near future, which slipped from 3.15 merge.
 
 - Device-specific fixes: mute LED support for Lenovo Ideapad,
   mic LED fix for HP laptops, more ASUS subwoofer quirks, yet more
   Dell laptop headset quirks
 
 - Make the HD-audio codec response a bit more robust
 
 - A few improvements on Realtek ALC282 / 283 about the pop noises
 
 - A couple of Intel HDMI fixes
 
 ASoC:
 - Lots of cleanups for enumerations; refactored lots of error prone
   original codes to use more modern APIs
 
 - Elimination of the ASoC level wrappers for I2C and SPI moving us
   closer to converting to regmap completely and avoiding some
   randconfig hassle
 
 - Provide both manually and transparently locked DAPM APIs rather than
   a mix of the two fixing some concurrency issues
 
 - Start converting CODEC drivers to use separate bus interface drivers
   rather than having them all in one file helping avoid dependency
   issues
 
 - DPCM support for Intel Haswell and Bay Trail platforms, lots of
   fixes
 
 - Lots of work on improvements for simple-card, DaVinci and the Renesas
   rcar drivers.
 
 - New drivers for Analog Devices ADAU1977, TI PCM512x and parts of the
   CSR SiRF SoC, TLV320AIC31XXX, Armada 370 DB, Cirrus cs42xx8
 
 - Fixes for the simple-card DAI format DT mess
 
 - DT support for a couple more devices.
 
 - Use of the tdm_slot mapping in a few drivers
 
 Others:
 - Support of reset_resume callback for improved S4 in USB-audio driver;
   the device with boot quirks have been little tested, which we need
   to watch out in this development cycle
 
 - Add PM support for ICE1712 driver (finally!);
   it's still pretty partial support, only for M-Audio devices

 "There have been lots of changes in ALSA core, HD-audio and ASoC, also
  most of PCI drivers touched by conversions of printks.  All these
  resulted in a high volume and wide ranged patch sets in this release.
  Many changes are fairly trivial, but also lots of nice cleanups and
  refactors.  There are a few new drivers, most notably, the Intel
  Haswell and Baytrail ASoC driver.

- ACPI core changes to make it create a struct acpi_device object for every
    device represented in the ACPI tables during all namespace scans regardless
    of the current status of that device.  In accordance with this, ACPI hotplug
    operations will not delete those objects, unless the underlying ACPI tables
    go away.
 
  - On top of the above, new sysfs attribute for ACPI device objects allowing
    user space to check device status by triggering the execution of _STA for
    its ACPI object.  From Srinivas Pandruvada.
 
  - ACPI core hotplug changes reducing code duplication, integrating the
    PCI root hotplug with the core and reworking container hotplug.
 
  - ACPI core simplifications making it use ACPI_COMPANION() in the code
    "glueing" ACPI device objects to "physical" devices.
 
  - ACPICA update to upstream version 20131218.  This adds support for the
    DBG2 and PCCT tables to ACPICA, fixes some bugs and improves debug
    facilities.  From Bob Moore, Lv Zheng and Betty Dall.
 
  - Init code change to carry out the early ACPI initialization earlier.
    That should allow us to use ACPI during the timekeeping initialization
    and possibly to simplify the EFI initialization too.  From Chun-Yi Lee.
 
  - Clenups of the inclusions of ACPI headers in many places all over from

Merge tag 'pm+acpi-3.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI and power management updates from Rafael Wysocki:
 "As far as the number of commits goes, the top spot belongs to ACPI
  this time with cpufreq in the second position and a handful of PM
  core, PNP and cpuidle updates.  They are fixes and cleanups mostly, as
  usual, with a couple of new features in the mix.

  The most visible change is probably that we will create struct
  acpi_device objects (visible in sysfs) for all devices represented in
  the ACPI tables regardless of their status and there will be a new
  sysfs attribute under those objects allowing user space to check that
  status via _STA.

  Consequently, ACPI device eject or generally hot-removal will not
  delete those objects, unless the table containing the corresponding
  namespace nodes is unloaded, which is extremely rare.  Also ACPI
  container hotplug will be handled quite a bit differently and cpufreq
  will support CPU boost ("turbo") generically and not only in the
  acpi-cpufreq driver.

  Specifics:

   - ACPI core changes to make it create a struct acpi_device object for
     every device represented in the ACPI tables during all namespace
     scans regardless of the current status of that device.  In
     accordance with this, ACPI hotplug operations will not delete those
     objects, unless the underlying ACPI tables go away.

Julia Lawall b30bb89f0f fujitsu-laptop: fix error return code
These functions mix the use of result and error.  In acpi_fujitsu_add,
result does not seem useful; it would seem reasonable to propagate the
return value of acpi_bus_update_power in an error case.  On the other hand,
in the case of acpi_fujitsu_hotkey_add, there is an initialization of
result that can lead to what looks like a failure case, but that does not
abort the function.  The variable result is kept for this case.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
(
if@p1 (\(ret < 0\|ret != 0\))
 { ... return ret; }
|
ret@p1 = 0
)
... when != ret = e1
    when != &ret
*if(...)
{
  ... when != ret = e2
      when forall
 return ret;
}

Hans de Goede 97f440c23f dell-laptop: Only install the i8042 filter when rfkill is active
Installing the i8042 filter is not useful on machines where rfkill is not
whitelisted, so move the filter installation into dell_setup_rfkill,
after the whitelist check.

This avoids doing a needless and potentially troublesome rfkill query
(dell_send_request(buf, 17, 11)) when the wireless Fn key gets pressed on
non whitelisted laptops.

This patch was written as a result of:
https://bugzilla.redhat.com/show_bug.cgi?id=1045807
It is not yet clear if this is related, but it is a good idea to not register
the i8042 filter in general.

David E. Box 997ab407d2 X86 platform: New BayTrail IOSF-SB MBI driver
Current Intel SOC cores use a MailBox Interface (MBI) to provide access to unit
devices connected to the system fabric. This driver implements access to this
interface on BayTrail platforms. This is a requirement for drivers that need
access to unit registers on the platform (e.g. accessing the PUNIT for power
management features such as RAPL). Serialized access is handled by all exported
routines with spinlocks.

The API includes 3 functions for access to unit registers:

int bt_mbi_read(u8 port, u8 opcode, u32 offset, u32 *mdr)
int bt_mbi_write(u8 port, u8 opcode, u32 offset, u32 mdr)
int bt_mbi_modify(u8 port, u8 opcode, u32 offset, u32 mdr, u32 mask)

port:	indicating the unit being accessed
opcode:	the read or write port specific opcode
offset:	the register offset within the port
mdr:	the register data to be read, written, or modified
mask:	bit locations in mdr to change

Returns nonzero on error

Note: GPU code handles access to the GFX unit. Therefore access to that unit
with this driver is disallowed to avoid conflicts.

Rashika Kheria 475879d651 drivers: platform: Include appropriate header file in mxm-wmi.c
This patch includes appropriate header file linux/mxm-wmi.h in
x86/mxm-wmi.c because functions mxm_wmi_call_mxds(), mxm_wmi_call_mxmx()

Lv Zheng 8b48463f89 ACPI: Clean up inclusions of ACPI header files
Replace direct inclusions of <acpi/acpi.h>, <acpi/acpi_bus.h> and
<acpi/acpi_drivers.h>, which are incorrect, with <linux/acpi.h>
inclusions and remove some inclusions of those files that aren't
necessary.

First of all, <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h>
should not be included directly from any files that are built for
CONFIG_ACPI unset, because that generally leads to build warnings about
undefined symbols in !CONFIG_ACPI builds.  For CONFIG_ACPI set,
<linux/acpi.h> includes those files and for CONFIG_ACPI unset it
provides stub ACPI symbols to be used in that case.

Second, there are ordering dependencies between those files that always
have to be met.  Namely, it is required that <acpi/acpi_bus.h> be included
prior to <acpi/acpi_drivers.h> so that the acpi_pci_root declarations the
latter depends on are always there.  And <acpi/acpi.h> which provides
basic ACPICA type declarations should always be included prior to any other
ACPI headers in CONFIG_ACPI builds.  That also is taken care of including
<linux/acpi.h> as appropriate.

Follow-up to commit 294d31e822 ("sony-laptop: don't change keyboard
backlight settings"): avoid messing up the state on resume.  Leave it to
what was before suspending as it's anyway likely that we still don't
know what value we should write to the EC registers.  This fix is also
required in 3.12

Some BIOS versions/Vaio models apparently ship with two nearly identical
functions to handle backlight related controls.
The only difference seems to be:
        If (LEqual (BUF1, 0x40))
        {
            Store (0x40, P80H)
            Store (BUF2, Local0)
-           And (Local0, One, Local0)
+           And (Local0, 0x03, Local0)
            Store (Local0, ^^H_EC.KLPC)
        }

Avoid erroring out on initialization and messing things up on cleanup
for now since we never call into these methods with anything different
than 1 or 0.

Hans de Goede 3f56588a79 dell-laptop: Don't read-back sw_state on machines with a hardware switch
On machines with a hardware switch, the blocking settings can not be changed
through a Fn + wireless-key combo, so there is no reason to read back the
blocking state from the BIOS.

Reading back is not only not necessary it is actually harmful, since on some
machines the blocking state will be cleared to all 0 after a wireless switch
toggle, even for radios not controlled by the hw-switch (yeah firmware bugs).

This causes "magic" changes to the sw_state. This is inconsistent with other
rfkill drivers which preserve the sw_state over a hw kill on / off.

-If the hardware radio switch is set to disable the radio, then userspace
 will still think it can use wireless and bluetooth.
-The wwan / 3g modem cannot be soft blocked without the dell-laptop rfkill
 functionality

I know the rfkill functionality was removed from the dell-laptop driver because
it caused more problems then it fixed, and the blacklist for it was growing out
of control.

But in the thread discussing this Dell mentioned that they only QA the rfkill
acpi interface on Latitudes and indeed there have been no blacklist entries
for Latitudes. Therefor I would like to bring the rfkill functionality back
only for Latitudes. This patch is a straight-forward revert. The next patch
in this set will drop the blacklist and replace it with a Latitude check.

Linus Torvalds eeab517b68 sound updates for 3.13-rc1
There are no too intrusive changes in this update batch.  The biggest
 LOC is found in the new DICE driver, and other small changes are
 scattered over the whole sound subtree (which is a common pattern).
 
 Below are highlights:
 
 - ALSA core:
   * Memory allocation support with genpool
   * Fix blocking in drain ioctl of compress_offload
 
 - HD-audio:
   * Improved AMD HDMI supports
   * Intel HDMI detection improvements
   * thinkpad_acpi mute-key integration
   * New PCI ID, New ALC255,285,293 codecs, CX20952
 
 - USB-audio:
   * New buffer size management
   * Clean up endpoint handling codes
 
 - ASoC:
   * Further work on the dmaengine helpers, including support for
     configuring the parameters for DMA by reading the capabilities of
     the DMA controller which removes some guesswork and magic numbers
     from drivers.
   * A refresh of the documentation.
   * Conversions of many drivers to direct regmap API usage in order to
     allow the ASoC level register I/O code to be removed, this will
     hopefully be completed by v3.14.
   * Support for using async register I/O in DAPM, reducing the time
     taken to implement power transitions on systems that support it.
 
 - Fireiwre: DICE driver
 
 - Lots of small fixes for bugs reported by Coverity

Do not touch keyboard backlight unless explicitly passed a module
parameter.  In this way we won't make wrong assumptions about what are
good default values since they actually are different from model to
model.

The only side effect is that we won't know what is the current value
until set via the sysfs attributes.
