Subject: [PATCH 3/3] PWM: update enable status when using the internal API
Date: Thu,  8 Dec 2016 18:04:41 +0100	[thread overview]
Message-ID: <1481216681-24393-3-git-send-email-jlu@pengutronix.de> (raw)
In-Reply-To: <1481216681-24393-1-git-send-email-jlu@pengutronix.de>

Without these, 'devinfo pwmX' will show enabled=0 even though the PWM
was enabled (for example by a pwm-backlight).
