From 56e5a3f043f0440cc0cce288e71134d1cb1b44a7 Mon Sep 17 00:00:00 2001 From: Paulo Zanoni Date: Fri, 25 Jan 2013 16:59:13 -0200 Subject: [PATCH] drm/i915: only disable enabled planes on intel_fb_restore_mode We should avoid touching registers that are on the power down well when we don't need to, because if we touch these registers when the power well is disabled we'll get tons of "unclaimed register" messages. This commit fixes some of these messages.
