BTW, this conflicts with commit e8a767e04dbc7b201cb17ab99dca723a3488b6d4
in msm-next. The resolution is trivial but just wanted to mention it.

I Just fetched msm-next and cherry-pick this patch over, no conflict
seen.
Is this conflict need to be fixed?

Oh sorry, I mean commit afc9b8b6bab8 ("drm/msm/dp: signal audio plugged
change at dp_pm_resume") which doesn't seem to be in msm-next. Maybe Rob
will resolve the conflict directly.

Yes, I just found that commit afc9b8b6bab8 ("drm/msm/dp: signal audio
plugged
