Ughh... I see that you probably copied the chunk from clk / regulator
implementation.  Let's please not copy those.  Input validation via
WARN_ON()s is nice when the interface is taking input from outside or
the code in question is complex / fragile.  Here, the code involved is
like 20 lines and self-contained.

Thanks.
