Hmm, it looks like we need this patch after all as we do have screwy
Lenovos with apparently 0x01 devices reporting 0 buttons. From
https://bugzilla.kernel.org/show_bug.cgi?id=196253

 thinkpad_acpi: ThinkPad BIOS R0DET87W (1.87 ), EC unknown
 thinkpad_acpi: Lenovo ThinkPad E470, model 20H1004SGE

 psmouse serio2: trackpoint: IBM TrackPoint firmware: 0x0e, buttons: 0/0

I'll ask them to try my patch and if it is indeed 0x01 device I'll apply
your patch.

Thanks.
