Perhaps the cases where clk_get returns NULL could have a comment
indicating that NULL does not represent a failure?

In 3.7.1, it looks like it might have been possible for NULL to be
returned by clk_get in arch/mips/loongson1/common/clock.c, but that
definition seems to be gone in a recent linux-next. The remaining
definitions look OK.
