Hi, Thorsten here, the Linux kernel's regression tracker.Something I'm wondering about is if it's possible for i8042 to detect the polarity is incorrect when it probes and
I noticed a regression report in bugzilla.kernel.org. As many (most?)
kernel developers don't keep an eye on it, I decided to forward it by mail.
Chuanhong Guo, apparently it's cause by a change of yours.
Note, you have to use bugzilla to reach the reporter, as I sadly[1] can
not CCed them in mails like this.

BTW: there apparently is another IRQ override needed for a different
machine. See https://bugzilla.kernel.org/show_bug.cgi?id=216804#c8 for

separate bug; that's also why this partly fall through the cracks here
:-/ ). The user is currently trying to create a patch.
