From 64d7d074acd52e1bdff621f2cb86c0aae9bcef80 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Wed, 7 Apr 2021 10:01:53 +0200 Subject: pwm: lpss: Don't modify HW state in .remove callback MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A consumer is expected to disable a PWM before calling pwm_put(). And if they didn't there is hopefully a good reason (or the consumer needs fixing). Also if disabling an enabled PWM was the right thing to do, this should better be done in the framework instead of in each low level driver. So drop the hardware modification from the .remove() callback.
