Indentation again.

This looks like you're open coding a supply widget.

This looks like you want a switch statement.

Remove empty functions.

Two problems here: one is that the power management should be in DAPM,
the other is that the _enable_clock_block() function is totally
pointless - it has only these two call locations and there is absolutely
no shared code between the enable and disable paths so they should just
be inlined.

This is disabling the clocks while the CODEC is still registered and
might be in use, you should unregister first.
