V4L/DVB: drivers/media/video/zoran: Use available error codes
Error codes are stored in res, but the return value is always 0. Return res instead. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ local idexpression x; constant C; @@ if (...) { ... x = -C ... when != x ( return <+...x...+>; | return NULL; | return; | * return ...; ) } // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
