Fwd: Kernel 6.4.4 breaks Elan Touchpad 1206

Fwd: Kernel 6.4.4 breaks Elan Touchpad 1206

[Bagas Sanjaya]

Hi,

I notice a regression report on Bugzilla [1]. Quoting from it:

See Bugzilla for the full thread:

To the reporter (Verot): Can you attach dmesg and lspci output?

Anyway, I'm adding this regression to be tracked by regzbot:

#regzbot introduced: 7b63a88bb62ba2 https://bugzilla.kernel.org/show_bug.cgi?id=217701
#regzbot title: OOB protocol access fix breaks Elan Touchpad 1206

Thanks.

Please don't as ELAN1206:00 04F3:30F1 looks like I2C-HID and not PS/2
device that 7b63a88bb62ba2 would affect.

Thanks.

Also 7b63a88bb62ba2 is present in 6.1 since v6.1.34.

Looks like the wrong culprit (see [1]), thus:

#regzbot introduced: v6.1..v6.4

Thanks.

No reply from the reporter in regards to required bisection, thus:

#regzbot inconclusive: not bisected, reporter MIA

Sorry for inconvenience.
