From: Ville Syrjälä <ville.syrj...@linux.intel.com> intel_crtc_prepare_cleared_state() is unintentionally losing the "inherited" flag. This will happen if intel_initial_commit() is forced to go through the full modeset calculations for whatever reason.
Afterwards the first real commit from userspace will not get forced to the full modeset path, and thus eg. audio state may not get recomputed properly. So if the monitor was already enabled during boot audio will not work until userspace itself does an explicit full modeset.
