From 2347aa7c34be284b266ab6b5f2bdf5daf14f582e Mon Sep 17 00:00:00 2001 From: Boris Brezillon Date: Thu, 14 Apr 2016 21:17:35 +0200 Subject: [PATCH] drm: i915: Explicitly apply PWM config extracted from pwm_args Call pwm_apply_args() just after requesting the PWM device so that the polarity and period are initialized according to the information provided in pwm_args. This is an intermediate state, and pwm_apply_args() should be dropped as soon as the atomic PWM infrastructure is in place and the driver makes use of it.
