To maintain compatibility with drivers that rely on v4l2_device storing
a pointer to itself in the device's drvdata, v4l2_device_register() will
keep doing so if the drvdata is NULL.

v4l: Move the media/v4l2-mediabus.h header to include/linux
v4l: Replace enums with fixed-sized fields in public structure
v4l: Rename
The v4l2_mbus_framefmt structure will be part of the public userspace
API and used (albeit indirectly) as an ioctl argument. As such, its size
must be fixed across userspace ABIs.
Replace the v4l2_field and v4l2_colorspace enums by __u32 fields.
Signed-off-by: Laurent Pinchart laurent.pinch
The header defines the v4l2_mbus_framefmt structure which will be used
by the V4L2 subdevs userspace API.
Change the type of the v4l2_mbus_framefmt::code field to __u32, as enum
sizes can differ between different ABIs on the same architectures.

Add a v4l2_subdev_pad_ops structure for the operations that need to be
performed at the pad level such as format-related operations.
Pad format-related operations use v4l2_mbus_framefmt instead of
v4l2_format.
