V4L/DVB (11387): Sensor orientation reporting
Add support to the SQ-905 driver to pass back to user space the sensor orientation information obtained from the camera during init. Modifies gspca and the videodev2.h header to create the necessary API. [mchehab@redhat.com: Changed "Output is" to "Frames are" at the comments, as suggested at LMML] Signed-off-by: Adam Baker <linux@baker-net.org.uk> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
