Subject: Re: Oops in hdac_hda_dev_probe (6.7-rc7)
Hi Takashi,
many thanks for your response. Your patch helps half-way: the oops goes
away, but so does the sound... With your patch, the decisive lines in dmesg
are:
sof-audio-pci-intel-tgl 0000:00:1f.3: Firmware info: version 2:2:0-57864
sof-audio-pci-intel-tgl 0000:00:1f.3: Firmware: ABI 3:22:1 Kernel ABI 3:23:0
sof_sdw sof_sdw: ASoC: CODEC DAI intel-hdmi-hifi1 not registered
sof_sdw sof_sdw: snd_soc_register_card failed -517
sof_sdw sof_sdw: ASoC: CODEC DAI intel-hdmi-hifi1 not registered
sof_sdw sof_sdw: snd_soc_register_card failed -517
platform sof_sdw: deferred probe pending
With a revert of the a0575b4add21, it is:
sof-audio-pci-intel-tgl 0000:00:1f.3: Firmware info: version 2:2:0-57864
sof-audio-pci-intel-tgl 0000:00:1f.3: Firmware: ABI 3:22:1 Kernel ABI 3:23:0

input: sof-soundwire HDMI/DP,pcm=7 as /devices/pci0000:00/0000:00:1f.3/sof_sdw/sound/card0/input16
Maybe this helps a bit further?
Best,
Dominik
