V4L/DVB (8466): cx23885: Bugfix - DVB Transport cards using DVB port VIDB/TS1 did not stream.
Certain DVB cards that have demodulators on TS1/VIDB were not streaming packets. This ensure the pin directions on PAD_CTRL are set correctly, solving the issue. Signed-off-by: Steven Toth <stoth@hauppauge.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
