From 4c23dea48b0d8d9da2ac0911f8cee105f4394281 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Fri, 18 May 2018 18:29:30 +0300 Subject: [PATCH] drm/i915: Implement the missing bits of assert_panel_unlocked() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add the missing eDP port handling into assert_panel_unlocked(). We now have intel_dp_port_enabled() which makes this trivial.
