Is there any great reason for > doing so? Yes, this certainly looks wrong. I must have forgotten to fix this up when of_pwm_simple_xlate() was converted to return a struct pwm_device instead of an int. Previous to that pwm_request_from_chip() would return NULL and -ENODEV seemed like the proper error code for that situation. I'll change this to just return pwm. Thanks, Thierry
