From adc103047e583497f675f0db32b758c8c2069633 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Tue, 31 Oct 2017 22:51:14 +0200 Subject: [PATCH] drm/i915: Eliminate some encoder->crtc usage from DP code MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Extract the current crtc from the crtc state rather than via the legacy encoder->crtc pointer whenever possible.
