Subject: [PATCH v6 156/164] staging: greybus: pwm: Make use of pwmchip_parent() accessor
Date: Wed, 14 Feb 2024 10:33:23 +0100 [thread overview]
Message-ID: <7e7517527b825a18ca10cb0faa837577d4f0ec8a.1707900770.git.u.kleine-koenig@pengutronix.de> (raw)
In-Reply-To: <cover.1707900770.git.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, use the accessor
function provided for exactly this purpose.
