Slightly intentional, because the assumption is providers already
have a clk_hw structure that they've created themselves when they
register a clkdev, whereas a struct clk is more likely to be an
error pointer because of clk_get(), etc. But I suppose we can add
the error check to ease registration in cases where providers are
using the basic types.
