Hi, Thorsten here, the Linux kernel's regression tracker.
Christian, I noticed a report about a regression in bugzilla.kernel.org
that appears to be caused by a change of yours:
de52aca4d9d56c ("usb: typec: ucsi: Never send a lone connector change
ack") [v6.10-rc1]
As many (most?) kernel developers don't keep an eye on the bug tracker,
I decided to write this mail. To quote from
https://bugzilla.kernel.org/show_bug.cgi?id=219108 :
> As the summary says, on the 2022 Asus Vivobook S15 OLED (model
> K3502ZA.306), the inbuilt keyboard has bad key registration after
> plugging the laptop in for charging. Sometimes, the keys pressed do not
> register at all, and sometimes they register very late. The keyboard
> works properly if I don't plug the laptop in to charge, and this issue
> doesn't manifest ever on kernels older than 6.6.37-1.
>
> I have tested every lts kernel after 6.6.37-1 and all of them have
> the same problem. I have also tested the latest mainline and zen
> kernels (versions 6.10.1 for both) and they too have the the same
> problem.> Once the laptop is plugged into it's charging cable, the
> keyboard fails and unplugging the laptop doesn't fix the situation.
> However, if I don't plug the laptop into it's charging cable, the
> problem never manifests itself. The charging cable itself is a usb

See the ticket for more details. The problem still happens with
6.11-rc1, a straight revert was not possible.
Note, you have to use bugzilla to reach the reporter, as I sadly[1] can
not CCed them in mails like this.
Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)

Everything you wanna know about Linux kernel regression tracking:
https://linux-regtracking.leemhuis.info/about/#tldr
If I did something stupid, please tell me, as explained on that page.
[1] because bugzilla.kernel.org tells users upon registration their
"email address will never be displayed to logged out users"
P.S.: let me use this mail to also add the report to the list of tracked
regressions to ensure it's doesn't fall through the cracks:
