Linus Torvalds 9f3938346a Merge branch 'kmap_atomic' of git://github.com/congwang/linux
Pull kmap_atomic cleanup from Cong Wang.

It's been in -next for a long time, and it gets rid of the (no longer
used) second argument to k[un]map_atomic().

Fix up a few trivial conflicts in various drivers, and do an "evil

Klaus Schmidinger 0e377819b9 [media] stb0899: fix the limits for signal strength values
stb0899: fix the limits for signal strength values

stb0899_read_signal_strength() adds an offset to the result of the table lookup.
That offset must correspond to the lowest value in the lookup table, to make sure
the result doesn't get below 0, which would mean a "very high" value since the
parameter is unsigned.
'strength' and 'snr' need to be initialized to 0 to make sure they have a
defined result in case there is no "internal->lock".

Ivan Kalvachev fa5527cd3f [media] em28xx: support for 2304:0242 PCTV QuatroStick (510e)
It is mostly copy/paste of the 520e code with setting GPIO7 removed
(no LED light).

I've worked on just released vanilla linux-3.3.0 kernel, so there may
be 1/2 lines offset to the internal working source, but most of the
code should apply cleanly.

I was able to get the DVB-C working (tuned and watched TV). Haven't
tested DVB-T (no signal atm).

Special thanks to everybody who worked on the code and to Antti
Palosaari and Devin Heitmueller who provided essential support on irc.

Hardware is based of:
Empia EM2884
Micronas DRX 3926K
NXP TDA18271HDC2

... + analog parts.
Analog is not supported currently. Only DVB-T and DVB-C.

There seems to be still	problems for locking DVB-C channels which have
strong signal. Attenuator helps. I think it is demodulator IF/RF AGC
issue. Lets fix it later. Patches are welcome.

Michael Krufky 9ab2393fc3 [media] pvrusb2: fix 7MHz & 8MHz DVB-T tuner support for HVR1900 rev D1F5
The D1F5 revision of the WinTV HVR-1900 uses a tda18271c2 tuner
instead of a tda18271c1 tuner as used in revision D1E9. To
account for this, we must hardcode the frontend configuration
to use the same IF frequency configuration for both revisions
of the device.

6MHz DVB-T is unaffected by this issue, as the recommended
IF Frequency configuration for 6MHz DVB-T is the same on both
c1 and c2 revisions of the tda18271 tuner.

Jonathan Corbet 121bbe254a [media] marvell-cam: fix the green screen of death
I had learned through hard experience that dinking around with the DMA
descriptors while the C1_DESC_ENA enable bit was set is a recipe for all
kinds of truly malicious behavior on the hardware's part, regardless of
whether the DMA engine is actually operating at the time.  That
notwithstanding, the driver did so dink, resulting in "green frame"
captures and the death of the system in random, spectacular ways.

Move the tweaking of C1_DESC_ENA to the same function that sets the
descriptor so we know that we'll never try to set a descriptor while that
bit is set.

Ezequiel García 5da6e98480 [media] rc: Pospone ir raw decoders loading until really needed
This changes rc_core to not load the IR decoders at load time,
postponing it to load only if a RC_DRIVER_IR_RAW device is
registered via rc_register_device.
We use a static boolean variable, to ensure decoders modules
are only loaded once.
Tested with rc-loopback device only.

Malcolm Priestley 593a2ce0ae [media] m88rs2000 ver 1.13 Correct deseqc and tuner gain functions
Remove incorrect SEC_MINI_B settings-TODO complete this section.

Correct break and remove return -EINVAL within set tone. It appears
there is a bug that occasionally something other than ON/OFF is
sent stalling the driver. Just continue and write back registers.

Set register b2 in setup. This is the set voltage pin which
isn't used in lmedm04 driver but it is always set to 0x1.

Correct the if statements in set_tuner_rf.

Just move tuner init and sleep to own functions from the demod

Gordon Hecker be4a5e7f0e [media] af9015: fix i2c failures for dual-tuner devices
The i2c failures were caused by enabling both i2c gates
at the same time while putting the tuners asleep.

This patch removes the init() and sleep() callbacks from the tuner,
to prevent frontend.c from calling
  i2c_gate_ctrl
  tuner init / sleep
  i2c_gate_ctrl
without holding the lock.
tuner init() and sleep() are instead called in frontend init() and
sleep().

Jean Delvare 3ef7675948 [media] dib0700: Drop useless check when remote key is pressed
struct dvb_usb_device *d can never be NULL so don't waste time
checking for this.

Rationale: the urb's context is set when usb_fill_bulk_urb() is called
in dib0700_rc_setup(), and never changes after that. d is dereferenced
unconditionally in dib0700_rc_setup() so it can't be NULL or the
driver would crash right away.

Laurent Pinchart ff732d281b [media] media: Initialize the media core with subsys_initcall()
Media-related drivers living outside drivers/media/ (such as the UVC
gadget driver in drivers/usb/gadget/) rely on the media core being
initialized before they're probed. As drivers/usb/ is linked before
drivers/media/, this is currently not the case and will lead to crashes
if the drivers are not compiled as modules.

Register media_devnode_init() as a subsys_initcall() instead of
module_init() to fix this.

Bhupesh Sharma ee981c6fac [media] V4L/v4l2-dev: Make 'videodev_init' as a subsys initcall
As the V4L2 based UVC webcam gadget (g_webcam) expects the
'videodev' to present when the 'webcam_bind' routine is called,
so 'videodev' should be available as early as possible.

Now, when 'g_webcam' is built as a module (i.e. not a part of
kernel) the late availability of 'videodev' is OK, but if
'g_webcam' is built statically as a part of the kernel,
the kernel crashes (a sample crash dump using Designware 2.0 UDC
is provided below).

To solve the same, this patch makes 'videodev_init' as a subsys initcall.
