Subject: [PATCH] ASoC: hdac_hda: Conditionally register dais for HDMI and Analog
Git-commit: a0575b4add21a243cc3257e75ad913cd5377d5f2
Patch-mainline: v6.7-rc5
References: git-fixes
The current driver is registering the same dais for each hdev found in the
system which results duplicated widgets to be registered and the kernel
log contains similar prints:
snd_hda_codec_realtek ehdaudio0D0: ASoC: sink widget AIF1TX overwritten

skl_hda_dsp_generic skl_hda_dsp_generic: ASoC: source widget Digital Codec Capture overwritten
skl_hda_dsp_generic skl_hda_dsp_generic: ASoC: source widget Alt Analog Codec Capture overwritten
To avoid such issue, split the dai array into HDMI and non HDMI array and
register them conditionally:
for HDMI hdev only register the dais needed for HDMI
for non HDMI hdev do not register the HDMI dais.
