The handling of VIDIOC_G/S_PRIORITY is now entirely done by the V4L2
core, so we can drop the g/s_priority ioctl ops.We do have to make sure though that when S_PRIORITY is called we check
that the driver used struct v4l2_fh. This check can be removed once all
drivers are converted to that structure.Signed-off-by: Hans Verkuil

The old debug field is renamed to dev_debug to ensure that existing drivers
(including out-of-tree drivers) that try to use the old name will no longer
compile. A comment has also been added that makes it explicit that drivers
shouldn't use this field.Additional bits have been added to the debug flag to be more fine-grained
when debugging, especially when dealing with streaming ioctls and read,
write and poll. You want to enable those explicitly to prevent flooding
the log when streaming unless you actually want to do that.Signed-off-by: Hans Verkuil

Simplify the debugging ioctls by creating the VIDIOC_DBG_G_CHIP_NAME ioctl.
This will eventually replace VIDIOC_DBG_G_CHIP_IDENT. Chip matching is done
by the name or index of subdevices or an index to a bridge chip. Most of this
can all be done automatically, so most drivers just need to provide get/set
register ops.
In particular, it is now possible to get/set subdev registers without
requiring assistance of the bridge driver.Signed-off-by: Hans Verkuil

This prepares struct video_device for easier integration with vb2.
It also introduces a new lock that protects the vb2_queue. It is up
to the driver to use it or not. And the driver can associate an owner

permitted for the calling filehandle.Signed-off-by: Hans Verkuil

Pull avoidance patches from Paul Gortmaker:
"Nearly every subsystem has some kind of header with a proto like:void foo(struct device *dev);
and yet there is no reason for most of these guys to care about the
sub fields within the device struct. This allows us to significantly
reduce the scope of headers including headers. For this instance, a
reduction of about 40% is achieved by replacing the include with the
simple fact that the device is some kind of a struct.Unlike the much larger module.h cleanup, this one is simply two
commits. One to fix the implicit users, and then one
to delete the device.h includes from the linux/include/ dir wherever
possible."* tag 'device-for-3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux:
device.h: audit and cleanup users in main include dir
device.h: cleanup users outside of linux/include (C files)

The header includes a lot of stuff, and
it in turn gets a lot of use just for the basic "struct device"
which appears so often.Clean up the users as follows:
1) For those headers only needing "struct device" as a pointer
in fcn args, replace the include with exactly that.2) For headers not really using anything from device.h, simply
delete the include altogether.3) For headers relying on getting device.h implicitly before
being included themselves, now explicitly include device.h4) For files in which doing #1 or #2 uncovers an implicit
dependency on some other header, fix by explicitly adding
the required header(s).Any C files that were implicitly relying on device.h to be
present have already been dealt with in advance.Total removals from #1 and #2: 51. Total additions coming
from #3: 9. Total other implicit dependencies from #4: 7.As of 3.3-rc1, there were 110, so a net removal of 42 gives
about a 38% reduction in device.h presence in include/*Signed-off-by: Paul Gortmaker
