I don't see it used by the leds-pwm driver on cleanup. The pwm-samsung driver does not disable the PWM channel according to my understanding of the code. But for example the pwm-renesas-tpu does stop the PWM timer on free. What is the correct behavior? Is the channel should be disabled on free then I agree that pwm_disable is not necessary. > > + hwmon_device_unregister(ctx->hwmon); > > + > > + return 0; > > +} > > + <snip> Best wishes, -- Kamil Debski Samsung R&D Institute Poland -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
