IT9135 RF tuner clock is coming from demodulator. We need enable it
early in demod init, before any tuner I/O. Currently it is enabled
by tuner driver itself, but it is too late and performance will be
reduced as some registers are not updated correctly. Clock is
disabled automatically when demod is put onto sleep.

That happens because the frontend was disabled by .config, but the

This patch removes the null test on ch. ch is initialized at the
beginning of the function to &demod->dtv_property_cache. Since demod
is dereferenced prior to the null test, demod must be a valid pointer,
and &demod->dtv_property_cache cannot be null.
