[media] drivers/media: fix dependencies in video mt9t001/mt9p031
Both mt9t001.c and mt9p031.c have two identical issues, those
being that they will need module.h inclusion for the upcoming
cleanup going on there, and that their dependencies don't limit
selection of configs that will fail to compile as follows:
The related config options are CONFIG_MEDIA_CONTROLLER and
CONFIG_VIDEO_V4L2_SUBDEV_API. Looking at the code, it appears
that the driver was never intended to work without these enabled,
so add a dependency on CONFIG_VIDEO_V4L2_SUBDEV_API, which in
turn already has a dependency on CONFIG_MEDIA_CONTROLLER.

Simplifies the locking by moving the em28xx_init_extension() call until

makes the second and subsequent "plugging" events logically identical to
the first "plugging" event when the em28xx-dvb and em28xx-alsa modules

Basically, em28xx_usb_probe() requests that em28xx-dvb be loaded and

serialised by the dev->lock mutex but the order that they happen in is
undefined. But this has always been the case anyway.

[media] em28xx: fix race on disconnect
This patch closes the race on the device and extension lists at USB disconnect
time. Previously, the device was removed from the device list during
em28xx_release_resources(), and then passed to the em28xx_close_extension()
function so that all extensions could run their fini() operations. However, this
left a (brief, theoretical, highly unlikely ;-)) window between these two calls
during which a new module could call em28xx_register_extension(). The result
would have been that the em28xx_usb_disconnect() function would also have passed
the device to the new extension's fini() function, despite never having called
the extension's init() function.
This patch also restores em28xx_close_extension()'s symmetry with
em28xx_init_extension(), and establishes the property that every device in the
device list must have been initialised for every extension in the extension list.

[media] stk-webcam.c: webcam LED bug fix
This is an improved version of the patch I sent a little ago.
The problem was:
On my DC-1125 webcam chip from Syntek, whenever the webcam turns
on, the LED light on it is turned on also and never turns off again unless
system is shut downed or restarted.
The previous version seemed to break some other laptop webcam work. Thanks
to Andrea Anacleto for the bug report and solution.

[media] media: Fix a UVC performance problem on systems with non-coherent DMA
The UVC driver uses usb_alloc_coherent() to allocate DMA data buffers.
On systems without coherent DMA this ends up allocating buffers in
uncached memory. The subsequent memcpy's done to coalesce the DMA
chunks into contiguous buffers then run VERY slowly. On a MIPS test
system the memcpy is about 200 times slower. This issue prevents the
system from keeping up with 720p YUYV data at 10fps.
The following patch uses kmalloc to alloc the DMA buffers instead of
usb_alloc_coherent on systems without coherent DMA. With this patch
the system was easily able to keep up with 720p at 10fps.

[media] omap3isp: video: Avoid crashes when pipeline set stream operation fails
If streaming can't be enabled on the pipeline, the DMA buffers queue is
not emptied. If the buffers then get freed the queue will end up
referencing free memory. This is usually not an issue, as the DMA queue
will be reinitialized the next time streaming is enabled, before
enabling the hardware.
However, if the sensor connected at the pipeline input is free-running,
the CCDC will start generating interrupts as soon as it gets powered up,
before the streaming gets enabled on the hardware. This will make the
CCDC interrupt handler access freed memory, causing a crash.
Reinitialize the DMA buffers queue in isp_video_streamon() if the error

[media] imon: don't parse scancodes until intf configured
The imon devices have either 1 or 2 usb interfaces on them, each wired
up to its own urb callback. The interface 0 urb callback is wired up
before the imon context's rc_dev pointer is filled in, which is
necessary for imon 0xffdc device auto-detection to work properly, but we
need to make sure we don't actually run the callback routines until
we've entirely filled in the necessary bits for each given interface,
lest we wind up oopsing. Technically, any imon device could have hit
this, but the issue is exacerbated on the 0xffdc devices, which send a
constant stream of interrupts, even when they have no valid key data.

[media] v4l2-ctrls: implement new volatile autocluster scheme
The problem tackled in this patch is how to handle volatile autoclusters
correctly. A volatile autocluster is a cluster of related controls where one
control is the control that toggles between manual and auto mode and the other
controls are the values for the manual mode. For example autogain and gain,
autoexposure and exposure, etc.
If the hardware lets you read out the automatically calculated manual values
while in automode, then those manual controls should be marked volatile.
gain value as calculated by the autogain circuitry, then you would mark the
gain control as volatile (i.e. continuously changing).
The question in such use cases is what to do when switching from the auto
mode to the manual mode. Should we switch to the last set manual values or
should the volatile values be copied and used as the initial manual values.
For example: suppose the mode is manual gain and gain is set to 5. Then
autogain is turned on and the gain is set by the hardware to 2. Finally
the user switches back to manual gain. What should the gain be? 2 or 5?
After a long discussion the decisions was made to keep the last value as
calculated by the auto mode (so 2 in the example above).
The reason is that webcams that do such things will adapt themselves to
the current light conditions and when you switch back to manual mode you
expect that you keep the same picture. If you would switch back to old
manual values, then that would give you a suddenly different picture,
which is jarring for the user.
Additionally, this would be difficult to implement in applications that
store and restore the control values at application exit and start.
If you want to keep the old manual values when you switch from auto to
manual, then there would have to be a way for applications to get hold
of those old values while in auto mode, but there isn't.
So this patch will do all the heavy lifting in v4l2-ctrls.c: if you go
from auto mode to manual mode and the manual controls are volatile, then
g_volatile_ctrl will be called to get the current values for the manual
controls before switching to manual mode.
