From: Alex Raimondi <raimondi@miromico.ch>
clk_get and clk_put may not be used from within interrupt context. Change comment to this function.
Signed-off-by: Alex Raimondi <raimondi@miromico.ch> Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com> --- 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?
