V4L/DVB (8372): gspca: Small ov6650 fixes.
1) Don't change the red and blue pre-gain's from their defaults 2) Actually make the powerline freq ctrl available to userspace Signed-off-by: Hans de Goede <j.w.r.degoede@hhs.nl> Signed-off-by: Jean-Francois Moine <moinejf@free.fr> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
