Subject[PATCH] Change comment in include linux/clk.h
Date
From: Alex Raimondi <raimondi@miromico.ch>

clk_get and clk_put may not be used from within interrupt
context. Change comment to this function.

I see several ARM implementation using mutexes for locking in these
functions. So I assume we never want to call them from interrupt
context, right?
