of being allocated and freed at capture start and stop.

7e64dc4c4d V4L/DVB (13899): gspca - all subdrivers: Make control descriptors constant.
The ctrls field of struct sd_desc is declared as const
in gspca.h. It is worth to initialize the content also with
constant values.

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:
