From 5ba001783ba6451fd3db0259d30549ca1fe91870 Mon Sep 17 00:00:00 2001 From: Tvrtko Ursulin Date: Thu, 3 Mar 2016 14:36:45 +0000 Subject: [PATCH] drm/i915: Do not wait atomically for display clocks MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Looks like this code does not need to wait atomically since it otherwise takes the mutex.
