The firmware version is in id.version, not id.model which is always
PSMOUSE_ALPS for ALPS devices.
The various fw versions are listed in <kernel>/drivers/input/mouse/alps.h and
are all hex numbers. Version 8 is actually 0x800, change the match
accordingly.
Expected side-effect: earlier versions of ALPS touchpads now lose their
(erroneous) size assignment.

This will thus work if the property is only set on a parent device, not on the
device directly.

These touchpads have a terrible resolution when two fingers are down, causing
scrolling to jump around a lot. That then turns into bug reports that we can't
do much about, the data is simply garbage.

Some model-specific information isn't available through udev properties. This
callout is used to query the device directly and set a property that we can
then match on for the hwdb entries.
This is geared for Elantech and ALPS touchpads where the firmware version is
the interesting bit. The udev rule is added already to match on that, note
that the callout doesn't do anything at this point. The various
touchpad-related things will be added separately.
