But as I said in some other email in response to Prashant, I'll go and
find out why the clk driver is returning NULL.

(Russell, while the clk API definition may allow NULL to be a legal clk
value, the actual implementation on Tegra at least doesn't consider NULL
to be a legal clk value, so it shouldn't be returned in the first
place). There's no issue here in the comprehension of the clk API.
