[CCing Takashi in case he is interested in this and/or wants to make my
life as regression tracker a little easier in the future]

Thx, in fact it was already merged:

https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=linux-6.0.y&id=02356311982bbb117310a27985fa8938e82c0b6e

That "#regzbot fixed-by: 02356311982b" above told my regression tracking
bot about the commit. I sadly had to do that manually, as Takashi used
the non-standard "BugLink" tag to link to the report, which Linus
doesn't want:

https://lore.kernel.org/all/CAHk-=wgs38ZrfPvy=nOwVkVzjpM3VFU1zobP37Fwd_h9iAD5JQ@mail.gmail.com/

To quote: ```please stop making up random tags that make no sense. Just
use "Link:"```

Maybe regzbot nevertheless should resolve a tracked regression as
resolved, if it sees BugLink to a tracked regression. But I think the
real solution is: checkpatch.pl should complain.

Ciao, Thorsten
