From: Paulo Zanoni Date: Tue, 17 Jul 2012 20:53:45 +0000 (-0300) Subject: drm/i915: add port field to struct intel_dp and use it X-Git-Tag: firefly_0821_release~3680^2~1922^2~61^2~48 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=ab9d7c302af858e1bc8f613c3a6f1eea3c4c0364;p=firefly-linux-kernel-4.4.55.git drm/i915: add port field to struct intel_dp and use it This will be needed for Haswell, but already has its uses here. This patch started as a small patch written patch by Shobhit Kumar, but it has changed so much that none of its original lines remain.
