Since internal to v4l2 the ioctl prototype is the same regardless of it
being called through .ioctl or .unlocked_ioctl, we need to convert it all
to the long return type of unlocked_ioctl.
Thanks to Jean-Francois Moine for posting an initial patch for this and
thus bringing it to our attention.

Introduce a struct v4l2_file_operations for v4l2 drivers.
Remove the unnecessary inode argument.
Move compat32 handling (and llseek) into the v4l2-dev core: this is now
handled in the v4l2 core and no longer in the drivers themselves.
Note that this changeset reverts an earlier patch that changed the return
type of__video_ioctl2 from int to long. This change will be reinstated
later in a much improved version.

Use the new video_drvdata(filp) function where it is safe to do so.

Remove the priv field and let video_get/set_drvdata use dev_get_drvdata
and dev_set_drvdata instead.
Convert all drivers that still used priv directly.

All drivers that call video_device_register where checked to see if they
set the release callback of struct video_device. Where that callback was
missing it was added.

The type and type2 fields were unused and so could be removed.
Instead add a vfl_type field that contains the type of the video
device.

Several V4L2 drivers still included videodev.h. Fix this.

According to an old comment this should have been removed in 2.6.15.

The functions in a header should not belong to another module. The prio functions
belong to v4l2-common.c, so move them to v4l2-common.h.
The ioctl functions belong to v4l2-ioctl.c, so create a new v4l2-ioctl.h header
and move those functions to it.

From: Mauro Carvalho Chehab <mchehab@infradead.org>
struct video_device used to define a .hardware field. While
initialized on severl drivers, this field is never used inside V4L.
However, drivers using it need to include the old V4L1 header.
This seems to cause compilation troubles with some random configs.
Better just to remove it from all drivers.

The videodev.h and videodev2.h describe the public API for V4L and V4L2.
It shouldn't have there any kernel-specific stuff. Those were moved to
v4l2-dev.h.
This patch removes some uneeded headers and include v4l2-common.h on all
V4L driver. This header includes device implementation of V4L2 API provided
on v4l2-dev.h as well as V4L2 internal ioctls that provides connections
between master driver and its i2c devices.

Now, drivers/media tree is complete. Only missing zoran36120
since this won't work and it is a good candidate to be removed
from kernel soon.
