[PATCH 03/12] ASoC: Intel: avs-hdaudio: remove redundant dapm routes

From: Brent Lu
Date: Sun Jun 11 2023 - 23:16:16 EST


Three routes "HDMI 0 Playback<-hdaudioB0D2-cpu0 Tx",
"HDMI 1 Playback<-hdaudioB0D2-cpu1 Tx" and
"HDMI 2 Playback<-hdaudioB0D2-cpu2 Tx" are created by
snd_soc_dapm_connect_dai_link_widgets() automatically. Remove the
duplicate routes.
