From da0dea8912697f725d5f1386a38cb035222e7468 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Wed, 28 Apr 2021 11:05:25 +0200 Subject: [PATCH] pwm: spear: Free resources only after pwmchip_remove() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Before pwmchip_remove() returns the PWM is expected to be functional. So remove the pwmchip before disabling the clocks. The check for pwmchip_remove()'s return value is dropped as this function returns effectively always 0 and returning an error in a remove callback is useless anyhow (as the device core ignores it and drops devm allocated resources).
