This patch fixes a bug which causes all histogram regions to start in the
top left corner of the image. The histogram region coordinates are 16 bit
values which share a 32 bit register. The bug is due to the region end
value assignments overwriting the region start values with zero.

The preview engine includes filters that consume columns and lines as
part of their operation, thus resulting in a cropped image. To allow
turning those filters on/off during streaming without affecting the
output image size, the driver adds additional cropping to make the total
number of cropped columns and lines constant regardless of which filters
are enabled.
This process needlessly includes the CFA filter, as whether the filter
is enabled only depends on the sink pad format, which can't change
during streaming.
Exclude the CFA filter from the preview engine margins.

Ming Lei reported:
IMO, there is a minor fault in the error handling path of
uvc_status_start() inside uvc_v4l2_open(), and the 'users' count should
have been decreased before usb_autopm_put_interface(). In theory, a [URB
resubmission] warning can be triggered when the device is opened just
between usb_autopm_put_interface() and atomic_dec(&stream->dev->users).
The fix is trivial.

Events for the iMon Knob pad where not correctly interpreted on ARM,
resulting in buggy mouse movements (cursor going straight out of the
screen), key pad only generating KEY_RIGHT and KEY_DOWN events.
A reproducer is:
int main(int argc, char ** argv)
{
        char rel_x = 0x00; printf("rel_x:%d @%s:%d\n", rel_x, __FILE__, __LINE__);
        rel_x = 0x0f; printf("rel_x:%d @%s:%d\n", rel_x, __FILE__, __LINE__);
        rel_x |= ~0x0f; printf("rel_x:%d @%s:%d\n", rel_x, __FILE__, __LINE__);
        return 0;
}
(running on x86 or amd64)
$ ./test
rel_x:0 @test.c:6
rel_x:15 @test.c:7
rel_x:-1 @test.c:8
(running on armv6)
rel_x:0 @test.c:6
rel_x:15 @test.c:7
rel_x:255 @test.c:8
Forcing the rel_x and rel_y variables as signed char fixes the issue.
