The current formulation of the bw_params loop uses the counter j as an
index for the first dimension of the bw_params array which is later
incremented by the variable i. It is evaluated correctly only, because j
is initialized to 0 at the beginning of the loop. I think that
explicitly using the index 0 better reflects the intent of the
expression.

[media] Use a named union in struct v4l2_ioctl_info
Hi Mauro,
struct v4l2_ioctl_info uses an anonymous union, which is initialized
in the v4l2_ioctls table.
Unfortunately gcc < 4.6 uses a non-standard syntax for that, so trying to
compile v4l2-ioctl.c with an older gcc will fail.
It is possible to work around this by testing the gcc version, but in this
case it is easier to make the union named since it is used in only a few
places.

[media] Avoid sysfs oops when an rc_dev's raw device is absent
For some reason, when the lirc daemon learns that a usb remote control
has been unplugged, it wants to read the sysfs attributes of the
disappearing device. This is useful for uncovering transient
inconsistencies, but less so for keeping the system running when such
inconsistencies exist.
Under some circumstances (like every time I unplug my dvb stick from
my laptop), lirc catches an rc_dev whose raw event handler has been
removed (presumably by ir_raw_event_unregister), and proceeds to
interrogate the raw protocols supported by the NULL pointer.
This patch avoids the NULL dereference, and ignores the issue of how
this state of affairs came about in the first place.

[media] Documentation: Add newline at end-of-file to files lacking one
This patch simply adds a newline character at end-of-file to those
files in Documentation/ that currently lack one.
This is done for a few different reasons:
A) It's rather annoying when you do "cat some_file.txt" that your
prompt/cursor ends up at the end of the last line of output rather
than on a new line.
B) Some tools that process files line-by-line may get confused by the
lack of a newline on the last line.
C) The "\ No newline at end of file" line in diffs annoys me for some
reason.
So, let's just add the missing newline once and for all.
