Stanse found that in ivtvfb_callback_cleanup and ivtvfb_callback_init
there are unneeded tests for itv being NULL. But itv is initialized
as container_of with non-zero offset in those functions, so it is
never NULL (even if v4l2_dev is). This was found because itv is

This patch fixes possible race conditions in queue management with SMP:
when a frame was completed, the irq function tried to use the next frame
buffer. At this time, it was possible that the application on an other
processor updated the frame pointer, making the image to point to a bad
buffer.
The patch contains two main changes:
- the image transfer uses the queue indexes which are protected against
  simultaneous memory access,
- the image pointer which is used for image concatenation is only set at
  interrupt level.
Some subdrivers which used the image pointer have been updated.

The problem may occur with SMP:
- a frame is completed at interrupt level (in gspca_frame_add with
  packet_type == LAST_PACKET,
- just after clearing the bit V4L2_BUF_FLAG_QUEUED and before setting
  the bit V4L2_BUF_FLAG_DONE, on the other processor, the application
  tries to requeue the same frame buffer,
- then, the qbuf function succeeds because ALL_FLAGS are not set.
The fix sets and resets the two flags in one instruction.

As pointed by Christoph Egger <siccegge@stud.informatik.uni-erlangen.de>,

The config Option DVB_DIBCOM_DEBUG was dropped while removing the dibusb
driver in favor of dvb-usb in 2005. However it remaind existant at some
places of the kernel config.

Instead of just removing the debug capability, the better is to just remove
the bad dependency, making the modprobe function always visible.

Spent a while last night getting device initialization packet captures
under Windows for all generations of devices. There are a few places
where we were doing things differently, and few things we were doing
that we don't need to do, particularly on gen3 hardware, and I *think*
one of those things is what was locking up my pinnacle hw from time to
time -- at least, its been perfectly well behaved every time its been
plugged in since making this change.

First up, we're adding a bit more to the gen1 init routine here. Its
not absolutely necessary, the hardware works the same both with and
without it, but I'd like to be consistent w/Windows here.

Second, DEVICE_RESET is never called when initializing either of my
gen3 devices, its only called for gen1 and gen2. The bits in the gen3
init after removing that, are safe (and interesting) to run on all
hardware, so there's no more gen3-specific init done, there's instead
a generic mceusb_get_parameters() that is run for all hardware.

Third, the gen3 flag isn't needed. We only care if hardware is gen3
during probe, so I've dropped that from the device flags struct.

Successfully tested on all three generations of mceusb hardware.

This should do the trick. Completely untested beyond compiling, but its
not exactly a complicated fix, and in practice, I'm not aware of anyone
ever actually tripping that locking bug, so there's zero functional change
in typical use here.

Since commit b4028437
the 'driver_data' field resides in device's struct device_private
which may be allocated by dev_set_drvdata() if device_private
struct was not allocated previously.

dev_set_drvdata() is used in video_set_drvdata() to set
the driver's private data pointer in v4l2 drivers. Setting
the private data _before_ registering the v4l2 device results
in a memory leak since __video_register_device() also calls
video_set_drvdata(), but after zeroing the device structure.
Thus, the reference to the previously allocated device_private
struct goes lost and a new device_private will be allocated.

All v4l drivers which call video_set_drvdata() _before_
calling video_register_device() are affected. The patch fixes
__video_register_device() to preserve previously allocated
device_private reference.

Caught by kmemleak.
