Will fix this in next version!

I agree!

Few lines below we are moving the digital clock from OFF to ON which
will change the state of registers. There are two callers, one from DAPM
RX CLK widget and other from soundwire clock gate! We will potentially
enter this path when we are resuming from clk pause state!

Will try to clean this up in next spin!
