Subject: Touchpad range : add another Macbook4,1 variant (#7749)
X-Git-Tag: v237~144

Touchpad range : add another Macbook4,1 variant (#7749)

#Add "Early 2008 Core 2 Duo/Penryn" Macbook4,1 match string to the existing touchpad range definition

##Symptoms
* Jerky/Jumpy cursor motion using touchpad
* "Axis value outside expected range" message in Xorg.0.log

##Fix
I followed the instructions described here :https://wayland.freedesktop.org/libinput/doc/latest/absolute_coordinate_ranges.html and came up with the following :

evdev:input:b0003v05ACp022A*
 EVDEV_ABS_00=256:1469:12
 EVDEV_ABS_01=256:829:12

The ranges and resolutions are the same as stated in the existing definition (+/- 2) so only add the match string.
