802971257a V4L/DVB (9638): drivers/media: use ARRAY_SIZE
ARRAY_SIZE is more concise to use when the size of an array is divided by
the size of its type or the size of its first element.

The semantic patch that makes this change is as follows:

5c4fa002b1 V4L/DVB (9690): gspca: Lock the subdrivers via module_get/put.
The previous subdriver protection against rmmod was done via the
file operations table in the device descriptor. On device disconnection
while streaming, the device structure was freed at close time, and the
module_put still used the module name in the freed area.
Now, explicit module get/put are done on open and close.

89a44b8a69 V4L/DVB (8720): gspca: V4L2_CAP_SENSOR_UPSIDE_DOWN added as a cap for some webcams.
This patch adds a V4L2_CAP_SENSOR_UPSIDE_DOWN flag to the capabilities flags,
and sets this flag for the Philips SPC200NC cam (which has its sensor installed
upside down). The same flag is also needed and added for the Philips SPC300NC.

Together with a patch to libv4l which adds flipping the image in software this
fixes the upside down display with the SPC200NC cam.
