This error situation got a specific reaction.

I imagine that a choice is available here for the error handling strategy.

* Return âERR_PTR(-ENOMEM)â as a strict response like in the other error case.

* Fix the setting âpll->rate_countâ at least (to be a bit more tolerant).
  Would any system users wonder then about the availability of only
  a single frequency (instead of possibly expected alternatives)?
