From 0c9501f823a40a061f755d3789c4705c9fe85f14 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Wed, 31 Aug 2016 10:18:12 +0200 Subject: backlight: pwm_bl: Handle gpio that can sleep Some backlight GPIOs might be connected to some i2c based expanders whose access might sleep. Since it's not in any critical path, use the cansleep variant of the GPIO API.
