mainline issue (apart from the backport of the culprit to 5.10.y Takashi

FWIW, that's "ASoC: Intel/SOF: use set_stream() instead of
set_tdm_slots() for HDAudio" from Pierre-Louis Bossart.

Thanks for the report and the patch. I CCed the relevant people for this.

[TLDR For the rest of the mail: : I'm adding this report to the list of
tracked Linux kernel regressions; the text you find below is based on a
few templates paragraphs you might have encountered already in similar
form. See link in footer if these mails annoy you.]

To be sure the issue doesn't fall through the cracks unnoticed, I'm
adding it to regzbot, the Linux kernel regression tracking bot:

#regzbot ^introduced 636110411ca726f19ef8e87b0be51bb9a4cdef06
#regzbot title alsa/asoc: kbl-r5514-5663-max hdmi stopped working
#regzbot ignore-activity

This isn't a regression? This issue or a fix for it are already
discussed somewhere else? It was fixed already? You want to clarify when
the regression started to happen? Or point out I got the title or
something else totally wrong? Then just reply and tell me -- ideally
while also telling regzbot about it, as explained by the page listed in
the footer of this mail.

Developers: When fixing the issue, remember to add 'Link:' tags pointing
to the report (the parent of this mail). See page linked in footer for
details.
