Are you sure that the function shouldn't check for requests? It seems like every caller is repeating the same check.
Sorry, I don't understand your comment here. When SYSCLK is disabled we need to disable DVFS so that the codec can't go into suspend in the illegal state of DVFS enabled but insifficient DCVDD. However, if dvfs_reqs==0 DVFS is already disabled so we can save some time.
Sure, but you repeat the same tests for dvfs_reqs at every call site which suggests it should be factored into the functions.
