From 62e1baa128f98006261308182fe3006d66b1bf61 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Wed, 13 Jul 2016 09:10:36 +0100 Subject: [PATCH] drm/i915: Remove superfluous powersave work flushing MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Instead of flushing the outstanding enabling, remember the requested frequency to apply when the powersave work runs.
