From 9b7b5736ffd5da6f8f6329ebe5f1829cbcf8afae Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Wed, 7 Jul 2021 18:28:27 +0200 Subject: [PATCH] pwm: mtk-disp: Don't check the return code of pwmchip_remove() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit pwmchip_remove() returns always 0. Don't use the value to make it possible to eventually change the function to return void. Also the driver core ignores the return value of mtk_disp_pwm_remove().
