Uwe Kleine-König 1271a7b98e pwm: Zero-initialize the pwm_state passed to driver's .get_state() 
This is just to ensure that .usage_power is properly initialized and
doesn't contain random stack data. The other members of struct pwm_state
should get a value assigned in a successful call to .get_state(). So in
the absence of bugs in driver implementations, this is only a safe-guard
and no fix.
