Fwd: Kernel 6.4.4 breaks Elan Touchpad 1206

[Bagas Sanjaya]

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

Thanks.
