Recent kernels properly clear the usb intfdata pointer when another
driver fails to bind (in the radio-shark* case the usbhid driver would try
to bind first.

When VIDIOC_ENUM_FREQ_BANDS is called for a driver that doesn't supply an
enum_freq_bands op, then it will fall back to reporting a single freq band
based on information from g_tuner or g_modulator.
Due to a bug this is an infinite list since the index field wasn't tested.
This patch fixes this and returns -EINVAL if index != 0.

Just a few fixes for problems found after updating v4l2-compliance to check
the frequency band enumeration.
Note that the i2c driver doesn't fill in bus_info, but since I can't test that
driver I've decided not to fix that.

Buffers marked as erroneous are recycled immediately by the driver if
the nodrop module parameter isn't set. The buffer payload size is reset
to 0, but the buffer bytesused field isn't. This results in the buffer
being immediately considered as complete, leading to an infinite loop in
interrupt context.
Fix the problem by resetting the bytesused field when recycling the
buffer.

The strcpy was being used to set the name of the board.
This was both wrong and redundant,
since the destination char* was read-only and
the name is set statically at compile time.
The type of the name field is changed to const char*
to prevent future errors.

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.

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.

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.
Version 2 incorporates changes recommended by Mauro Carvalho Chehab
(-ENODEV instead of -EINVAL, and a signed-off-by).

This patch will always set the field to INTERLACED (this fixes a bug were a driver should
never return FIELD_ANY), and will default to YUYV pixelformat if an unknown pixelformat
was specified.
This way S/TRY_FMT will always return a valid format struct.

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.
