[Patch] psm(4) ClickPad detection (was Re: Lenovo W540 so far)

[Ivan Rokotov]

Well, with patched synaptics driver + patched kernel = no touchpad at
all, no keyboard (Ctrl+Alt+F1 worked). With patched synaptics +
unpatched kernel = everything works as earlier. (Bluetooth mouse works
all time time.)

I post the relevant part of the logs + my xorg.conf, just for the case.

# cat dmesg.today | grep psm0
