From b32962f87acdc52a9734d15e9053e0f8fa1dcc9e Mon Sep 17 00:00:00 2001 From: Maarten Lankhorst Date: Mon, 1 May 2017 15:38:03 +0200 Subject: [PATCH] drm/i915: Handle force_audio correctly in intel_sdvo Do the same as other connectors, attempt to detect hdmi audio in the detect() callback, and only use the force_audio property as override. Compute has_audio in pipe_config, and use that value instead of the probed value directly.
