From b8aea3d1f408445f7683b47de09a8c6209c36409 Mon Sep 17 00:00:00 2001 From: Imre Deak Date: Wed, 20 Apr 2016 20:27:55 +0300 Subject: [PATCH] drm/i915/bxt: Don't uninit/init display core twice during system suspend/resume Atm, we run the BSpec display core uninit/init sequences twice during system suspend/resume. While this shouldn't cause any problem, it's redundant, so get rid of the duplicate call.
