This didn't print anything on resume, so `psmouse->private` apparently

Thank you for reporting this and providing the information!

need_deactivate is never being set on the smbdev struct since it's elantouch.
On this machine SMBus is not used so it falls back to PS/2 mode.
When this occurs the psmouse->private pointer is being replaced but
psmouse_smbus_reconnect is still being called on resume expecting smbdev.
That explains why when it is setup needs_deactivate is false, but on resume it
has somehow changed to true.

I've submitted a fix for this at
https://lore.kernel.org/all/20231004005729.3943515-1-jefferymiller@google.com/ (local)
and it should resolve this issue for you.

Thanks,
