Oliver Endriss <o.endriss@gmx.de> pointed out: Imho not a good idea, as the frontend thread calls - fe->ops.tuner_ops.init - fe->ops.tuner_ops.sleep If you remove fe->ops.i2c_gate_ctrl, init and sleep will fail, because gate_ctrl was never called... -- Signed-off-by: Manu Abraham <manu@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
