I just moved the condition out from the function and called it when the
condition is true.
if (!drv->power_specified)
set_power_states(drv);
But please, drop this patch too. I noticed there is an overlap with the
next patch I have in my series but not published.
Accidentally I removed "cpuidle_curr_driver = drv;"
Sorry for the inconvenience. Time for me to go to bed :)
