From 87b63f73e248343d527d2ea6c0b9241b89a60680 Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Wed, 14 Feb 2024 10:32:25 +0100 Subject: pwm: samsung: Make use of pwmchip_parent() accessor MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
