V4L/DVB (4495): Fix "no data from ZL10353 based USB tuner" problem
Force parallel transport stream output on the ZL10353 attached to a bluebird device. Addresses the problem where a frontend lock was observed, but no MPEG transport data was received. Signed-off-by: Chris Pascoe <c.pascoe@itee.uq.edu.au> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
