V4L/DVB (9346): Optimization: Enable gate in a symmetric/disciplined way,
rather than implementing different ways leading to confusion. This allows multiple gate_enable/disable's in the tuner_read/write functions, thereby lesser number of I/O operations throughout, eventually leading to better results. As a side effect demods that detect the STOP bit for auto closing of the gate can be avoided, thereby a very minimal gain in disabling the auto detect feature as well. Improves readability on the device control. Signed-off-by: Manu Abraham <manu@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
