Hello Guenter,
I would rather avoid the function pointer cast.
How about defining an auxiliary function for the cleanup action?
clk_disable_unprepare() is static inline, so gcc will have to
define an auxiliary function either way. What do you think?
Not really. It would just make it more complicated to replace the
call with devm_clk_prepare_enable(), should it ever find its way
into the light of day.
