From 3140aafb22edeab0cc41f15f53b12a118c0ac215 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 15 Jul 2019 23:14:53 +0200 Subject: [PATCH] ALSA: hda/hdmi - Fix i915 reverse port/pin mapping The recent fix for Icelake HDMI codec introduced the mapping from pin NID to the i915 gfx port number. However, it forgot the reverse mapping from the port number to the pin NID that is used in the ELD notifier callback. As a result, it's processed to a wrong widget and gives a warning like snd_hda_codec_hdmi hdaudioC0D2: HDMI: pin nid 5 not registered This patch corrects it with a proper reverse mapping function.
