Hi, this is your Linux kernel regression tracker.

Linux-Input developers, do you have any idea what might be causing the
problem outline below? It's a post 5.17 regression in mainline that was
reported to bugzilla.kernel.org about a week ago, but didn't even get a
single reply. Might be some other subsystem that is causing it, not sure.

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)

P.S.: As the Linux kernel's regression tracker I deal with a lot of
reports and sometimes miss something important when writing mails like
this. If that's the case here, don't hesitate to tell me in a public
reply, it's in everyone's interest to set the public record straight.
