b016760054 V4L/DVB (10644): v4l2-subdev: rename dev field to v4l2_dev 
Remain consistent in the naming: fields pointing to v4l2_device should
be called v4l2_dev. There are too many device-like entities without
adding to the confusion by mixing naming conventions.

aecde8b53b V4L/DVB (10141): v4l2: debugging API changed to match against driver name instead of ID. 
Since the i2c driver ID will be removed in the near future we have to
modify the v4l2 debugging API to use the driver name instead of driver ID.

Note that this API is not used in applications other than v4l2-dbg.cpp
as it is for debugging and testing only.

Should anyone use the old VIDIOC_G_CHIP_IDENT, then this will be logged
with a warning that it is deprecated and will be removed in 2.6.30.

069b747931 V4L/DVB (10138): v4l2-ioctl: change to long return type to match unlocked_ioctl. 
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.

2a1fcdf082 V4L/DVB (9820): v4l2: add v4l2_device and v4l2_subdev structs to the v4l2 framework. 
Start implementing a proper v4l2 framework as discussed during the
Linux Plumbers Conference 2008.

Introduces v4l2_device (for device instances) and v4l2_subdev (representing
sub-device instances).
