V4L/DVB (12082): gspca_stv06xx: Add support for st6422 bridge and sensor
Add support for st6422 bridge and sensor to the stv06xx gspca sub driver, tested with: Logitech QuickCam Messenger 046d:08f0 ST6422 integrated Logitech QuickCam Mess. Plus 046d:08f6 ST6422 integrated Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
