From 56696c1c04f43f1dcf8fba5842de6122c112b6a0 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Wed, 14 Feb 2024 10:32:23 +0100 Subject: [PATCH] pwm: samsung: Simplify code to determine the pwmchip's parent device MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit There is already a pointer to the pwmchip, make use of it directly instead of using the struct samsung_pwm_chip *our_chip just obtained from it. This also has the advantage of not using struct samsung_pwm_chip::chip any more which will be dropped soon.
