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.
