MAINTAINERS & files: Canonize the e-mails I use at files

From now on, I'll start using my @kernel.org as my development e-mail.

As such, let's remove the entries that point to the old
mchehab@s-opensource.com at MAINTAINERS file.

For the files written with a copyright with mchehab@s-opensource,
let's keep Samsung on their names, using mchehab+samsung@kernel.org,
in order to keep pointing to my employer, with sponsors the work.

For the files written before I join Samsung (on July, 4 2013),
let's just use mchehab@kernel.org.

For bug reports, we can simply point to just kernel.org, as
this will reach my mchehab+samsung inbox anyway.

[media] BKL: trivial BKL removal from V4L2 radio drivers

The patch converts a bunch of V4L2 radio drivers to unlocked_ioctl.

These are all simple conversions: most already had a lock and so the ioctl
fop could simply be replaced by unlocked_ioctl.

radio-miropcm20.c was converted to use the new V4L2 core lock.

While doing this work I noticed that many of these drivers initialized
some more fields or muted audio or something like that *after* creating
the device node. This should be done before the device node is created
to prevent problems. Especially hal tends to grab a device node as soon
as it is created.

In one or two cases the mutex_init was even done after the device creation!

Introduce a struct v4l2_file_operations for v4l2 drivers.

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.

[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.

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.

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!
