From bdeba794c2f1b067dc6f029bcf0fd12ff507afa7 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 13 Aug 2019 17:11:28 +0200 Subject: [PATCH] ALSA: hda - Drop unsol event handler for Intel HDMI codecs We don't need to deal with the unsol events for Intel chips that are tied with the graphics via audio component notifier. Although the presence of the audio component is checked at the beginning of hdmi_unsol_event(), better to short cut by dropping unsol_event ops.
