From bd90123c4973821775d7ffae9891ad36017702a9 Mon Sep 17 00:00:00 2001 From: Imre Deak Date: Mon, 29 Feb 2016 22:49:02 +0200 Subject: [PATCH] drm/i915/skl: Fix power domain suspend sequence During system suspend we need to first disable power wells then unitialize the display core. In case power well support is disabled we did this in the wrong order, so fix this up.
