From: Paulo Zanoni Date: Fri, 3 May 2013 15:15:40 +0000 (-0300) Subject: drm/i915: only disable DDI sound if intel_crtc->eld_vld X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c77bf5659deb9405ef61080c148e47d2c8ee31e5;p=linux-beck.git drm/i915: only disable DDI sound if intel_crtc->eld_vld We already have the same check on intel_enable_ddi. This patch prevents "unclaimed register" messages when the power well is disabled. V2: Reset intel_crtc->eld_vld to false after the mode_set function. V3: Add both "type != INTEL_OUTPUT_EDP" requested.
