Subject: [PATCH] pwm: atmel: Free resources only after pwmchip_remove()
Date: Wed, 24 Mar 2021 20:56:35 +0100 [thread overview]
Message-ID: <20210324195635.75037-1-u.kleine-koenig@pengutronix.de> (raw)
Before pwmchip_remove() returns the PWM is expected to be functional. So
remove the pwmchip before disabling the clock.
