psm(4) support for Elantech touchpads

[Matthias Apitz]

Hello Vladimir,

I own an Acer C720 (aka Chromebook) which worked fine concerning the
touchpad with the cyapa driver in CURRENT. After a repair in Acer.com
they said that they have had to change the keyboard and the touchpad and
it now does not attach anymore to the cyapa.ko; it seems that it was
replace by an Elan TP and while googlöing for support I found your
posting from September 2015. I have applied the patch to r292778 but the
code is not walked through because it says on verbose boot:

atkbd0: [GIANT-LOCKED]
random: harvesting attach, 8 bytes (4 bits) from atkbd0
psm0: unable to allocate IRQ

Any ideas about this? Thanks in advance

	matthias
