msizanoen 754ff5060d Input: alps - fix compatibility with -funsigned-char
The AlpsPS/2 code previously relied on the assumption that `char` is a
signed type, which was true on x86 platforms (the only place where this
driver is used) before kernel 6.2. However, on 6.2 and later, this
assumption is broken due to the introduction of -funsigned-char as a new
global compiler flag.

Fix this by explicitly specifying the signedness of `char` when sign
extending the values received from the device.

Jason A. Donenfeld 8980f19094 Input: focaltech - use explicitly signed char type
The recent change of -funsigned-char causes additions of negative
numbers to become additions of large positive numbers, leading to wrong
calculations of mouse movement. Change these casts to be explicitly
signed, to take into account negative offsets.

Linus Torvalds ff0c7e1862 ARM: unused boardfile removal for 6.3
This is a follow-up to the deprecation of most of the old-style board
 files that was merged in linux-6.0, removing them for good.
 
 This branch is almost exclusively dead code removal based on those
 annotations. Some device driver removals went through separate subsystem
 trees, but the majority is in the same branch, in order to better handle
 dependencies between the patches and avoid breaking bisection.
 
 Unfortunately that leads to merge conflicts against other changes in the
 subsystem trees, but they should all be trivial to resolve by removing
 the files.
 
 See commit 7d0d3fa733 ("Merge tag 'arm-boardfiles-6.0' of
 git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc") for the
 description of which machines were marked unused and are now removed. The
 only removals that got postponed are Terastation WXL (mv78xx0) and
 Jornada720 (StrongARM1100), which turned out to still have potential
 users.

Steven Rostedt (Google) 292a089d78 treewide: Convert del_timer*() to timer_shutdown*()
Due to several bugs caused by timers being re-armed after they are
shutdown and just before they are freed, a new state of timers was added
called "shutdown".  After a timer is set to this state, then it can no
longer be re-armed.

The following script was run to find all the trivial locations where
del_timer() or del_timer_sync() is called in the same function that the
object holding the timer is freed.  It also ignores any locations where
the timer->function is modified between the del_timer*() and the free(),
as that is not considered a "trivial" case.

This was created by using a coccinelle script and the following
commands:

    $ cat timer.cocci
    @@
    expression ptr, slab;
    identifier timer, rfield;
    @@
    (
    -       del_timer(&ptr->timer);
    +       timer_shutdown(&ptr->timer);
    |
    -       del_timer_sync(&ptr->timer);
    +       timer_shutdown_sync(&ptr->timer);
    )
      ... when strict
          when != ptr->timer
    (
            kfree_rcu(ptr, rfield);

Raul E Rangel a6d4439af5 Input: elan_i2c - use PM subsystem to manage wake irq
The Elan I2C touchpad driver is currently manually managing the wake
IRQ. This change removes the explicit enable_irq_wake/disable_irq_wake
and instead relies on the PM subsystem. This is done by calling
dev_pm_set_wake_irq.

i2c_device_probe already calls dev_pm_set_wake_irq when using device
tree, and i2c_device_remove also already calls dev_pm_clear_wake_irq.
There could be some device tree systems that have incorrectly declared
`wake` capabilities, so this change will set the wake irq if one is
missing. This matches the previous behavior.

I tested this on an ACPI system where the touchpad doesn't have _PRW
defined. I verified I can still wake the system and that the wake source
was the touchpad IRQ GPIO.

Mark Pearson 2fd003ee8a Input: synaptics - disable Intertouch for Lenovo T14 and P14s AMD G1
Since intertouch was enabled for the T14 and P14s AMD G1 laptops there
have been a number of reports of touchpads not working well.

Debugging this with Synaptics they noted that intertouch should not be
enabled as SMBUS host notify is not available on these laptops.

Reverting the previous commit (e4ce4d3a93)
to restore functionality back to what it was.

Note - we are working with Synaptics to see if there is a better
solution, but nothing is confirmed as yet.

Noticed this while trying to debug some unrelated issues: this laptop has

Sync up with the latest I2C code base to get updated prototype of I2C
bus remove() method.
2022-08-17 12:30:00 -07:00
Uwe Kleine-König ed5c2f5fd1 i2c: Make remove callback return void
The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

Zongmin Zhou c853246539 Input: vmmouse - disable vmmouse before entering suspend mode
Currently, when trying to suspend and resume with VirtualPS/2 VMMouse
there is an error message after resuming:

	psmouse serio1: vmmouse: Unable to re-enable mouse when reconnecting, err: -6

and the mouse will no longer be operable, requiring full rescan to find a
another driver to use for the port.

This error is due to QEMU still generating PS2 events which the kernel is
not consuming until resume time, where they interfere with mouse
identification and ultimately resulting in an error getting
VMMOUSE_VERSION_ID.

Test scenario:

1) start virtual machine with qemu command "vmport=on"
2) click suspend botton to enter suspend mode
3) resume and observe the error message in the kernel logs

Let's fix this by disabling the vmmouse in its reset handler. This will
notify qemu to stop vmmouse and remove the handler.

Arnd Bergmann 08d3df8c81 ARM: pxa: split up mach/hardware.h
The mach/hardware.h is included in lots of places, and it provides
three different things on pxa:

- the cpu_is_pxa* macros
- an indirect inclusion of mach/addr-map.h
- the __REG() and io_pv2() helper macros

Split it up into separate <linux/soc/pxa/cpu.h> and mach/pxa-regs.h
headers, then change all the files that use mach/hardware.h to
include the exact set of those three headers that they actually
need, allowing for further more targeted cleanup.

linux/soc/pxa/cpu.h can remain permanently exported and is now in
a global location along with similar headers. pxa-regs.h and
addr-map.h are only used in a very small number of drivers now
and can be moved to arch/arm/mach-pxa/ directly when those drivers
are to pass the necessary data as resources.

Hans de Goede 04b7762e37 Input: elan_i2c - fix regulator enable count imbalance after suspend/resume
Before these changes elan_suspend() would only disable the regulator
when device_may_wakeup() returns false; whereas elan_resume() would
unconditionally enable it, leading to an enable count imbalance when
device_may_wakeup() returns true.

This triggers the "WARN_ON(regulator->enable_count)" in regulator_put()
when the elan_i2c driver gets unbound, this happens e.g. with the
hot-plugable dock with Elan I2C touchpad for the Asus TF103C 2-in-1.

Fix this by making the regulator_enable() call also be conditional
on device_may_wakeup() returning false.

Dmitry Torokhov 7b1f781f2d Input: psmouse - set up dependency between PS/2 and SMBus companions
When we switch from emulated PS/2 to native (RMI4 or Elan) protocols, we
create SMBus companion devices that are attached to I2C/SMBus controllers.
However, when suspending and resuming, we also need to make sure that we
take into account the PS/2 device they are associated with, so that PS/2
device is suspended after the companion and resumed before it, otherwise
companions will not work properly. Before I2C devices were marked for
asynchronous suspend/resume, this ordering happened naturally, but now we
need to enforce it by establishing device links, with PS/2 devices being
suppliers and SMBus companions being consumers.

Pavel Skripkin 9f3ccdc3f6 Input: appletouch - initialize work before device registration
Syzbot has reported warning in __flush_work(). This warning is caused by
work->func == NULL, which means missing work initialization.

This may happen, since input_dev->close() calls
cancel_work_sync(&dev->work), but dev->work initalization happens _after_
input_register_device() call.

So this patch moves dev->work initialization before registering input
device
