Hello,
This is second part, which just adds the functionality to existing code
base, also including support of vid inputs for it8712 chip.
This patch was also briefly reviewed by Jean Delvare.
Signed-off-by: Rudolf Marek <r.marek at sh.cvut.cz>
Oh I forgot, sorry. Both patches are against 2.6.8rc2
Regards
Rudolf
