From 8c0216f377406c7613b67bd18755889026284192 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Wed, 4 Jan 2017 09:40:54 +0100 Subject: [PATCH] pwm: Remove .can_sleep from struct pwm_chip All PWM devices have been marked as "might sleep" since v4.5, there is no longer a need to differentiate on a per-chip basis.
