From 6d7f7ffbcdb9c043409cee13664d13a07c70bbc4 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Wed, 7 Jul 2021 18:28:33 +0200 Subject: [PATCH] pwm: sifive: Don't check the return code of pwmchip_remove() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit [ Upstream commit ceb2c2842f3664dcc4e6d8cb317e1e83bb81b1e5 ] 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 pwm_sifive_remove().
