cf69b808ca V4L/DVB: au8522_decoder: g/s_fmt doesn't do anything: remove
g/s_fmt is going to disappear, so if it is not doing anything, then
just remove it.

ea01b11a07 V4L/DVB: mt9v011: add enum/try/s_mbus_fmt support
Note that this driver is only used by em28xx and that em28xx does not
actually call the enum/try/s_fmt ops of mt9v011. So these functions
have never been tested.

And in fact the driver really implements cropping instead of scaling. So it
seems to be doing the wrong thing :-(

e3a5ee73e7 V4L/DVB: pvrusb2: Fix kernel oops on device tear-down
pvrusb2: Delete sysfs class device as the _very_ last step, after
we're sure that all driver contexts have gone away first.  This is
important because it appears that there isn't any protection from a
struct device instance reference a deleted struct class instance.  The
assumption in the kernel code appears to be that the class instance is
assumed to be around for the life of the device.  So we can't let the
class instance go away until all referencing device instances are
gone; this is ensured by delaying removal of the class instance until
after the driver contexts have all gone away.  This bug has been
present for a very long time but it didn't apparently become malignant
until recently (probably because of other changes in the kernel).

pvrusb2: Fix oops caused by touching deleted memory after
unregistration.  This bug was introduced when we had started using
video_device_node_name() - that function was being called potentially
after the underlying structure (referenced by that function) had been
deleted.  The fix rearranges things slightly so that the function is
called before destruction takes place.

997ea58eb9 USB: rename usb_buffer_alloc() and usb_buffer_free() users
For more clearance what the functions actually do,

  usb_buffer_alloc() is renamed to usb_alloc_coherent()
  usb_buffer_free()  is renamed to usb_free_coherent()

They should only be used in code which really needs DMA coherency.

All call sites have been changed accordingly, except for staging
drivers.

D'oh. Okay, here's v2, should fix that buglet too.

This hack was used when the imon driver was using internal key lookup
routines, but became dead weight when the driver was converted to use
ir-core's key lookup routines. These bits simply didn't get removed,
drop 'em now.

Pointed out by Dan Carpenter.

v2: fix possible attempt to access beyond end of key table array,
also pointed out by Dan.

If my dvb device is removed while in use, I got the following oops:

If there are users (for example users == -2) :
 - dvb_unregister_frontend :
 - stop kernel thread with dvb_frontend_stop :
  - fepriv->exit = 1;
  - thread loop catch stop event and break while loop
  - fepriv->thread = NULL; and fepriv->exit = 0;
 - dvb_unregister_frontend wait on "fepriv->dvbdev->wait_queue" that fepriv->dvbdev->users==-1.
The user finish :
 - dvb_frontend_release - set users to -1
 - don't wait wait_queue because fepriv->exit != 1

=> dvb_unregister_frontend never exit the wait queue.

8b661b508b V4L/DVB: s2255drv: remove dead code
My concern initially was we dereference "dev" in the parameter list to
s2255_dev_err() but it turns out that code path is never used.
The s2255_stop_readpipe() is only called from one place and "dev" is
never null.  So this patch just removes the whole condition here.

The original code didn't handle the case where vdev was not found so I
added a check for that.

b9245d80c3 V4L/DVB: ov511: cleanup: remove unneeded null check
We dereference "ov" unconditionally throughout the function so there is
no way it can be NULL here.  This code has been around for ages so if
it were possible for "ov" to be NULL someone would have complained.
