[PATCH libinput v3 0/4] Disable laptop touchpad on lid close

[James Ye]

Although a laptop touchpad is usually not accessible when the lid is closed,
some laptop models suffer from a hardware bug where the touchpad can be
activated even if the lid is closed.  This bug can be worked around by disabling
the touchpad when the lid is closed.

This patch set adds:
1: switch interface[1]
2: evdev dispatch interface for laptop lid switches
3: mechanism for pairing touchpad with lid, and disabling the touchpad
4: test cases

Changes since v2:
removed set 1 (merged in systemd[2])
set 2 (now set 1):
 - removed tablet mode enum
set 3 (now set 2):
 - check for SW_LID in lid_switch_process
set 4 (now set 3):
 - check if event is a switch event
set 5 (now set 4):
 - rebased off master
 - renamed lid.c to test-lid.c

Cheers,
  James
