Subject: [PATCH][next] pwm: Fix incorrect variable used in error message

The dev_err message is reporting the incorrect return value ret_tohw,
it should be reporting the value in ret_fromhw. Fix this by using
ret_fromhw instead of ret_tohw.

Fixes: 6c5126c6406d ("pwm: Provide new consumer API functions for waveforms")
