Hi All,

This series fixes a somewhat special bug where sometimes the
kbd/touchpad do not work on certain 2-in-1s with 360 degree
(yoga) hinges, which use 2 accelerometers to allow figuring out the
angle between the display and the base.

The display accelerometer ACPI device / fwnode has a special ACPI
method which allows suppressing kbd + touchpads events when folded
into tablet-mode and sometimes the event suppression gets enabled
by default, this series calls the ACPI method at probe time to
disable the suppression, fixing the kbd/touchpad not working.

A web-search shows various reports about this issue in forums and such,
so it would be good if we can get these 2 patches added to a 5.10-rc#
as a bugfix, as I indicated in the Subject prefix.

Regards,

Hans
