From c268444a2cecabc0ab567ca275662d80fa0ac813 Mon Sep 17 00:00:00 2001 From: Animesh Manna Date: Wed, 26 Aug 2015 01:36:06 +0530 Subject: [PATCH] drm/i915/skl Remove the call for csr uninitialization from suspend path This patch remove the function call to set the firmware loading status as uninitialized during suspend. Dmc firmware will restore the firmware in normal suspend. In previous patch added a check to directly read the hardware status and load the firmware if got reset during resume from suspend-hibernation.
