From bbf35e9defb9a6d1564dd56c7d113f07b9799873 Mon Sep 17 00:00:00 2001 From: Maarten Lankhorst Date: Tue, 8 Nov 2016 13:55:38 +0100 Subject: [PATCH] drm/i915: Pass atomic state to intel_audio_codec_enable, v2. MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit drm_select_eld requires mode_config.mutex and connection_mutex because it looks at the connector list and at the legacy encoders. This is not required, because when we call audio_codec_enable we know which connector it was called for, so pass the state. This also removes having to look at crtc->config. Changes since v1: - Use intel_crtc->pipe instead of drm_crtc_index.
