[media] soc-camera: change order of removing device
As our general practice, we use stream off before we close
the video node. So that the drivers its stream off function
would be called before its remove function.
But for the case for ctrl+c, the program would be force closed.
We have no chance to call that vb2 stream off from user space,
but directly call the remove function in soc_camera.
In that common code of soc_camera:
ici->ops->remove(icd);
if (ici->ops->init_videobuf2)
vb2_queue_release(&icd->vb2_vidq);
It would first call the device remove function, then release vb2,
in which stream off function is called. Thus it create different
order for the driver.
This patch change the order to make driver see the same sequence
to make it happy.

[media] pwc: Rework locking
While testing gtk-v4l's new ctrl event code, I hit the following deadlock
in the pwc driver:
Thread 1:
-Does a VIDIOC_G_CTRL
-video2_ioctl takes the modlock
-video2_ioctl calls v4l2_g_ctrl
-v4l2_g_ctrl takes the ctrl_handler lock
-v4l2_g_ctrl calls pwc_g_volatile_ctrl
-pwc_g_volatile_ctrl releases the modlock as the usb transfer can take a
significant amount of time and we don't want to block DQBUF / QBUF too long
Thread 2:
-Does a VIDIOC_FOO_CTRL
-video2_ioctl takes the modlock
-video2_ioctl calls v4l2_foo_ctrl
-v4l2_foo_ctrl blocks while trying to take the ctrl_handler lock
Thread 1:
-Blocks while trying to re-take the modlock, as its caller will eventually
unlock that
Now we have thread 1 waiting for the modlock while holding the ctrl_handler
lock and thread 2 waiting for the ctrl_handler lock while holding the
modlock -> deadlock.
Conclusion:
1) We cannot unlock modlock from pwc_s_ctrl / pwc_g_volatile_ctrl,
but this can cause QBUF / DQBUF to block for up to a full second
2) After evaluating various option I came to the conclusion that pwc should
stop using the v4l2 core locking, and instead do its own locking
Thus this patch stops pwc using the v4l2 core locking, and replaces that with
it doing its own locking where necessary.

Adding support for the CX23888 DIF.
Changes regression tested against the HVR1700 and HVR1800.
Split out much of the set and init handling of the cx23885 based
cards into their own functions. Added the DIF initialization code
for each supported IF.
Updated the cx23885 code to correctly initialize cx23888 based
video/audio decoders.

First in a series of patches that adds support to the cx23885 driver
for CX23888 analog video handling. Raw and MPEG video support is
being added for the HVR1850 driver in the patch, and the following
series of patches.
Some basic cx23885 driver cleanup. Partly to add HVR1850 support
and partly to allow -417.c V4L2 calls to be routed through thr
driver core and handled in a single place.
Make a number of core driver functions available to the -417.c
driver to streamline the driver.
Add the analog tuner ops definition so we can reach/tune the
hardware when we need to. Added the tff field so 888 based cards
(which have a weird field ordering issue) can be accomodated
and worked around in the driver.
