a3a9e287da V4L/DVB (13547): radio: add trivial checks on the tuner and type args.
Many radio drivers did not check the tuner and type field correctly
for g/s_frequency. These checks have now been added.

bec43661b1 V4L/DVB (10135): v4l2: introduce v4l2_file_operations.
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.

a399810ca6 V4L/DVB (8482): videodev: move all ioctl callbacks to a new v4l2_ioctl_ops struct
All ioctl callbacks are now stored in a new v4l2_ioctl_ops struct. Drivers fill in
a const struct v4l2_ioctl_ops and video_device just contains a const pointer to it.

This ensures a clean separation between the const ops struct and the non-const
video_device struct.

b2cb200f0d V4L/DVB (7377): radio-sf16fmr2.c: fix volume handling
As reported by  Roel Kluin <12o3l@tiscali.nl>:
in drivers/media/radio/radio-sf16fmr2.c:319:

for (i = 0; i < ARRAY_SIZE(radio_qctrl); i++) {
	if ((fmr2->card_type != 11)
        	        && V4L2_CID_AUDIO_VOLUME)
	        radio_qctrl[i].step = 65535;
        ...

I don't understand this '&& V4L2_CID_AUDIO_VOLUME'

While fixing this issue, I've revisited the volume control code and fixed
CodingStyle on the changed procedures.

fa027c2a0a [PATCH] mark struct file_operations const 4
Many struct file_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.

The videodev.h and videodev2.h describe the public API for V4L and V4L2.

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.

0d0fbf8152 V4L (926_2): Moves compat32 functions from fs to v4l subsystem
This moves the 32 bit ioctl compatibility handlers for
Video4Linux into a new file and adds explicit calls to them
to each v4l device driver.

Unfortunately, there does not seem to be any code handling
the v4l2 ioctls, so quite often the code goes through two
separate conversions, first from 32 bit v4l to 64 bit v4l,
and from there to 64 bit v4l2. My patch does not change
that, so there is still much room for improvement.

Also, some drivers have additional ioctl numbers, for
which the conversion should be handled internally to
that driver.

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
