V4L/DVB (10972): zl10353: i2c_gate_ctrl bug fix
zl10353 i2c-gate was always closed and due to that devices having tuner behind i2c-gate were broken. Add module configuration which allows disabling i2c-gate only when really needed. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
