e37559b22c [media] vb2: stop_streaming should return void
The vb2 core ignores any return code from the stop_streaming op.
And there really isn't anything it can do anyway in case of an error.
So change the return type to void and update any drivers that implement it.

The int return gave drivers the idea that this operation could actually
fail, but that's really not the case.

The pwc amd sdr-msi3101 drivers both had this construction:

        if (mutex_lock_interruptible(&s->v4l2_lock))
                return -ERESTARTSYS;

This has been updated to just call mutex_lock(). The stop_streaming op
expects this to really stop streaming and I very much doubt this will
work reliably if stop_streaming just returns without really stopping the
DMA.

b80cb8dc41 [media] media: s5p_mfc: remove s5p_mfc_get_node_type() function
s5p_mfc_get_node_type() relies on get_index() helper function, which in
turn relies on video_device index numbers assigned on driver
registration. All this code is not really needed, because there is
already access to respective video_device structures via common
s5p_mfc_dev structure. This fixes the issues introduced by patch
1056e4388b ("v4l2-dev: Fix race condition
on __video_register_device"), which has been merged in v3.12-rc1.

76a4ddbd52 [media] s5p-mfc: call wake_up_dev if in suspend mode
If a frame is still decoding when system enters suspend mode, we wait
on the device queue for a interrupt condition. This sometimes leads to a
timeout because the device queue might not be woken up everytime.
Usually, the context queue gets woken up when that context's frame gets
decoded. This patch adds a condition to wake up the device queue along
with the context queue when the system is in suspend mode.
Since the device queue is now woken up, we don't have to check the
context's int_cond flag while waiting. Also, we can skip calling try_run
after waking up the device queue to ensure that we don't have to wait
for more than one frame to be processed.

The $obj-m/$obj-y vars should be adding new modules to build, not
overriding it. So, it should never use
	$obj-y := foo.o
instead, it should use:
	$obj-y += foo.o

Failing to do that is very bad, as it will suppress needed modules.

69c9fe6f4a [media] s5p-mfc: v4l2 controls setup routine moved to initialization code
Callback .start_streaming is called once for every queue,
so v4l2_ctrl_handler_setup was called twice during stream start.
Moving v4l2_ctrl_handler_setup to context initialization
reduces numbers of calls and seems to be more consistent with API.

fc906b6d18 [media] s5p-mfc: Remove special clock usage in driver
MFC uses two clocks - MFC gate clock and special clock
which is named as "sclk_mfc" in exynos4 and "aclk_333" in
exynos5 SoC. The driver was doing just a clk_prepare on
this special clock without a clk_enable call. As this
sclk is the parent of gate clock, it gets prepared and
enabled along with the gate clock. So there is no need
for the driver to use this sclk. This patch removes the
sclk usage from driver.

It assigns existing but not used s5p_mfc_get_dec_status_v6() function to the

e9d98ddc0a [media] s5p-mfc: Update v6 encoder buffer alloc
MFC v6 needs minimum number of output buffers to be queued
for encoder depending on the stream type and profile.
The patch modifies the driver so that encoding cannot be
started with lesser number of OUTPUT buffers than required.
This also fixes the crash happeninig during multi instance
encoder-decoder simultaneous run due to memory allocation
happening from interrupt context.

Pull media update from Mauro Carvalho Chehab:

 - OF documentation and patches at core and drivers, to be used by for
   embedded media systems

 - some I2C drivers used on go7007 were rewritten/promoted from staging:
   sony-btf-mpx, tw2804, tw9903, tw9906, wis-ov7640, wis-uda1342

 - add fimc-is driver (Exynos)

 - add a new radio driver: radio-si476x

 - add a two new tuners: r820t and tuner_it913x

 - split camera code on em28xx driver and add more models

 - the cypress firmware load is used outside dvb usb drivers.  So, move
   it to a common directory to make easier to re-use it

 - siano media driver updated to work with sms2270 devices

 - several work done in order to promote go7007 and solo6x1x out of
   staging (still, there are some pending issues)

 - several API compliance fixes at v4l2 drivers that don't behave as
   expected

 - as usual, lots of driver fixes, improvements, cleanups and new device
   addition at the existing drivers.
