Re: [PATCH] ACPI: EC: Ignore ECDT tables with an invalid ID string

[Ilya K]

Hello folks!

It looks like this change makes the touchpad stop being detected entirely on my ThinkBook 14 G7 IML[0].

The kernel log says: > ACPI: EC: [Firmware Bug]: Ignoring ECDT due to invalid ID string "_SB.PC00.LPCB.EC0"
Which looks technically invalid, but also probably important? :)

Reverting the change makes things work again. I'm going to try a firmware update and pray to
whatever dark gods are responsible for Lenovo firmware that they fixed their ACPI tables, but
that requires getting Windows on the machine, so it'll take a bit.
