My static checker complains that we dereference "state" inside the call
to fft_to_mode() before checking for NULL. The comments say that it is
possible for "state" to be NULL so I have moved the dereference after
the check.

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 code attempts to maintain a "user format" and a "sensor format",
but in this case it looks like a typo is passing the user format down
to the sensor.
This was preventing display of video at anything other than 640x480.

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.

Use list_for_each_entry and perform some other induced simplifications.

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.

the driver duplicates the module_pci_driver code,
how?
module_pci_driver is used for those drivers whose
init and exit paths does only register and unregister
to pci API and nothing else.
so use the module_pci_driver macro instead

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.
