From 7ff666bc4b821650a03cadeb4108c77328c98c0a Mon Sep 17 00:00:00 2001 From: Boris Brezillon Date: Thu, 14 Apr 2016 21:17:32 +0200 Subject: [PATCH] backlight: lm3630a: 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.
