V4L/DVB (13563): gspca - zc3xx: Bad sensor probe of the webcam 0ac8:305b.
- probe the webcam (probe sequence from ms-win trace) - update tax5130c init sequences from ms-win newer driver - update tas5130c sequences from ms-win trace - add some comments in the probe code Signed-off-by: Jean-Francois Moine <moinejf@free.fr> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
