[media] em28xx: replug locking cleanup

Simplifies the locking by moving the em28xx_init_extension() call until
em28xx_usb_probe() has finished with the dev->lock mutex. It therefore
makes the second and subsequent "plugging" events logically identical to
the first "plugging" event when the em28xx-dvb and em28xx-alsa modules
must be loaded (i.e. registered).

Basically, em28xx_usb_probe() requests that em28xx-dvb be loaded and
also triggers udev to initialise the V4L2 devices. These two events are
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 deadlock when unplugging and replugging a DVB adapter

This fixes the deadlock that occurs with either multiple PCTV 290e adapters or when a single PCTV 290e adapter is replugged.

For DVB devices, the device lock must now *not* be held when adding/removing either a device or an extension to the respective lists. (Because em28xx_init_dvb() will want to take the lock instead).

Conversely, for Audio-Only devices, the device lock *must* be held when adding/removing either a device or an extension to the respective lists.

[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] 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
path to make sure this situation won't happen.

[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] STV0288 frontend provide wider carrier search and DVB-S2 drop out. resend

The following patch provides wider carrier search.

As with existing code search starts at MSB aligned. The boundary
is widened to start at -9.  In order to save time, if no carrier is
detected at the start it advances to the next alignment until carrier
is found.

The stv0288 will detect a DVB-S2 carrier on all steps , a
time out of 11 steps is introduced to drop out of the loop.

In stv0288_set_symbol carrier and timing loops are restored to
default values (inittab) before setting the symbol rate on each tune. A
slight drift was noticed with full scan in the higher IF frequencies of

[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.
