Why not combine these conditionals in to one. Why do you need 3 separate
blocks?

Adding line here will help readability.

Add a goto NOTSUPPORTED; Makes it easier.
You can simplify this logic a lot.

Adding blank lines will improve readability.

tuner_ctl_analog_step_inc() and tuner_ctl_analog_step_dec() has lots of
common code. The only real difference is calls to
cec_msg_tuner_step_increment() vs. cec_msg_tuner_step_decrement()
Also the error logic is very hard to read.
