Subject: [PATCH v3 012/108] pwm: img: Make use of parent device pointer in driver data
Date: Tue, 21 Nov 2023 14:49:14 +0100 [thread overview]
Message-ID: <20231121134901.208535-13-u.kleine-koenig@pengutronix.de> (raw)
In-Reply-To: <20231121134901.208535-1-u.kleine-koenig@pengutronix.de>
struct pwm_chip::dev is about to change. To not have to touch this
driver in the same commit as struct pwm_chip::dev, make use of the
already existing pointer to the parent device in driver data.
