Hi,

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

...

Description: When booting into Linux 6.4.4, system no longer recognizes touchpad input (confirmed with xinput). On the lts release, 6.1.39, the input is still recognized.

Additional info:

• package version(s): Linux 6.4.4, 6.1.39
• Device: ELAN1206:00 04F3:30F1 Touchpad

Steps to reproduce:

• Install 6.4.4 with Elan Touchpad 1206
• Reboot

The issue might be related to bisected commit id: 7b63a88bb62ba2ddf5fcd956be85fe46624628b9 This is the only recent commit related to Elantech drivers I've noticed that may have broken the input.

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

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

Thanks.

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

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

Thanks.
