[Intel-gfx] [PATCH 2/6] drm/i915: Pass atomic state to intel_audio_codec_enable

Wed Sep 7 09:06:29 UTC 2016


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.
