From fa90ecefdc656b1e25af18251707907dbc1e7609 Mon Sep 17 00:00:00 2001 From: Paulo Zanoni Date: Fri, 26 Oct 2012 19:05:44 -0200 Subject: [PATCH] drm/i915: simplify assignments inside intel_dp.c - Replace container_of with enc_to_intel_dp. - Walk through less structures when making assignments. - Rename some variables to keep our naming standards. As a bonus, this will reduce the usage of "struct intel_dp", making the future patch that introduces intel_digital_port smaller and easier to review.
