From 4563654fddc05a572f889373ba22abc616b3aa1f Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Mon, 10 Feb 2020 22:22:39 +0100 Subject: pwm: imx27: Don't disable clocks at device remove time MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The .remove() callback is not supposed to modify hardware state. This is in the responsibility of the PWM consumer. After the PWM was disabled the clocks are off (apart from a bug that is fixed in the next patch), so unbinding the driver either stops the PWM (which it should not) or disables already disabled clocks yielding warnings from the clk core. So just drop the call to disable the clocks. (Which BTW was also in the wrong order because the call makes the PWM unfunctional and so should have come only after pwmchip_remove()).
