Some 2-in-1 laptops / convertibles with 360° (yoga-style) hinges,
use 2 KXCJ91008 accelerometers:
1 in their display using an ACPI HID of "KIOX010A"; and
1 in their base using an ACPI HID of "KIOX020A"
Since in this case we know the location of each accelerometer,
set the label for the accelerometers to the standardized
"accel-display" resp. "accel-base" labels. This way userspace
can use the labels to get the location.
This was tested on a Medion Akoya E2228T MD60250.
