V4L/DVB (9987): gspca - spca561: Control changes for Rev72a.
- move the rev12a sequence from setcontrast to end of start - add the white balance control for rev72a - adjust the contrast formula Signed-off-by: Jean-Francois Moine <moinejf@free.fr> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
