From 2085cc5d3ccdc804eb320d1403be31cf28650552 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Wed, 29 Nov 2017 18:43:03 +0200 Subject: [PATCH] drm/i915: Fix has_audio readout for DDI A MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Transcoder EDP does not support audio. Let's not try to read the state of the audio enable bit HSW_AUD_PIN_ELD_CP_VLD based on the pipe when using transcoder EDP. While at it make the function static and flatten it.
