[PATCH v2 libinput 09/10] pad: Allow for a hook to test the sysfs path
Peter Hutterer

Wed Jun 15 06:37:42 UTC 2016
If the LIBINPUT_TEST_TABLET_PAD_SYSFS_PATH udev property is set, use that as
sysfs base path. This enables us to re-create the expected sysfs struct in
some temporary folder during tests, thus allowing for tests of the mode
groups' correct behaviours.
