From 7c8615d8f9faf7a33ad528a012e097631599207f Mon Sep 17 00:00:00 2001 From: Paulo Zanoni Date: Fri, 7 Mar 2014 20:08:14 -0300 Subject: [PATCH] drm/i915: remove dev_priv->pc8.enabled It was just being used on debugfs and on a WARN inside hsw_set_power_well. But now that we PC8 is part of runtime PM and we get/put runtime PM when we get/put any power domain, we shouldn't need the WARN anymore. v2: - Rebase. v3: - Rebase.
