Fix bugs in the cx18 AC3 control implementation that would have affected
ivtv and other drivers via the cx2341x module.  Bring AC3 controls
behavior into comliance with V4L2 specification.  Thanks to Hans Verkuil

Initial addition of controls to set AC-3 audio encoding for the CX23418 - it
does not work yet due to firmware or cx18 driver issues.  This change affects
the common cx2341x and ivtv modules due to shared structures and

A redundant PLL divisior update for the I2S master clock after AV core

The name of the pvrusb2 module is not likely to ever change, and there
are plenty of other places where the name is directly coded, so there
is little utility in using a macro to infer the module name here.  In
addition, using that macro complicates other uses of the driver
involving older kernels where this macro works differently.  Yes I
know for many places we don't have to worry about that.  But my
alternative is that I have to build special logic in the pvrusb2
standalone driver to special-case what is otherwise costmetic and that
is just plain nuts for something as trivial as this, especially since
this change does not at all have any compile time or run time impact
on the driver.  I'm just removing a nicety that didn't have a lot of
value here to begin with.

It appears that various v4l-dvb drivers are changing to require

implements an automatic issuance of VIDIOC_INT_INIT when a module is

Previous v4l-dvb changeset id 4cc8ed11e2e0 changed the pvrusb2-hdw
internal API regarding i2c chip debug register access.  However that
change failed to also update the corresponding function comment
describing the API.  As driver maintained I never saw a request for an
ack on that change; there probably should have been one especially
since the manner in which this API operates was changed - its
interface is now entangled with a v4l specific struct and I would have
preferred to keep this API clear of moving-target v4l-isms such as
this one if at all possible which is why I had done it the way I did
before.  But whatever.  This commit at least fixes the comment issue.

This patch adds the capability of selecting between 4 different inputs
on vivi driver. Input 0 is the normal color bar, while inputs 1-3 are
modified color bars.

This allows testing input selection on userspace applications and
serves as an implementation model for other drivers.

The current approach allows a maximum of 10 different inputs, since the
input name generator assumes that we need just one digit to present the
input. It shouldn't be hard to modify it to present a bigger name of
inputs, but, in fact, it doesn't make much sense of doing it for this
test driver.

check_unsafe_exec() also notes whether the fs_struct is being
shared by more threads than will get killed by the exec, and if so
sets LSM_UNSAFE_SHARE to make bprm_set_creds() careful about euid.
But /proc/<pid>/cwd and /proc/<pid>/root lookups make transient
use of get_fs_struct(), which also raises that sharing count.

This might occasionally cause a setuid program not to change euid,
in the same way as happened with files->count (check_unsafe_exec
also looks at sighand->count, but /proc doesn't raise that one).

We'd prefer exec not to unshare fs_struct: so fix this in procfs,
replacing get_fs_struct() by get_fs_path(), which does path_get
while still holding task_lock, instead of raising fs->count.

Joe Malicki reports that setuid sometimes doesn't: very rarely,
a setuid root program does not get root euid; and, by the way,
they have a health check running lsof every few minutes.

Right, check_unsafe_exec() notes whether the files_struct is being
shared by more threads than will get killed by the exec, and if so
sets LSM_UNSAFE_SHARE to make bprm_set_creds() careful about euid.
But /proc/<pid>/fd and /proc/<pid>/fdinfo lookups make transient
use of get_files_struct(), which also raises that sharing count.

There's a rather simple fix for this: exec's check on files->count
has been redundant ever since 2.6.1 made it unshare_files() (except
while compat_do_execve() omitted to do so) - just remove that check.

[Note to -stable: this patch will not apply before 2.6.29: earlier
releases should just remove the files->count line from unsafe_exec().]

2.6.26's commit fd8328be
"sanitize handling of shared descriptor tables in failing execve()"
moved the unshare_files() from flush_old_exec() and several binfmts
to the head of do_execve(); but forgot to make the same change to
compat_do_execve(), leaving a CLONE_FILES files_struct shared across
exec from a 32-bit process on a 64-bit kernel.

It's arguable whether the files_struct really ought to be unshared
across exec; but 2.6.1 made that so to stop the loading binary's fd
leaking into other threads, and a 32-bit process on a 64-bit kernel
ought to behave in the same way as 32 on 32 and 64 on 64.
