V4L/DVB (6776): ivtv: Some general fixes
Fix "warning: Using plain integer as NULL pointer". Convert 'x < y ? x : y' to use min() instead. Signed-off-by: Richard Knutsson <ricknu-0@student.ltu.se> Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
