Also, the dvb_frontend.c makes calls to i2c_gate_ctrl() at various

Ok, thanks for the pointer. The gate control is never called
externally in reality. I will wait a little while for this patch to be
applied. It removes the exported function and thereby an unnecessary
dereference.

There is one call to the gate control function from stv6110x_attach.
This is needed to set up the clock output divider to the correct value
before the demodulators clock is configured.
This could be solved by calling tuner_init before setting up the master
clock in stv090x_init but that only helps on single tuner devices. On
dual tuner devices you can only open the adapter that works with the
second tuner. Then you will have the case that the master clock is set
without having the clock output divider of first tuner initialized to
the correct value.
