We don't have spdx license tag yet for copyleft-next, and although
when using dual gplv2 or copyleft-next gplv2 applies I did fail to see
can use spdx for dual licensing such as:

# SPDX-License-Identifier: GPL-2.0-or-later OR BSD-2-Clause

You mean copyleft-next. Yes I'd have to add that. Given that we already
have two test drivers with that license I'll go ahead and add that.

The faul injection code I added follows the exact license for sysfs. The
only interaction with the test_sysfs and sysfs is an exported symbol
for a completion structure. The other dual gpl OR copyleft-next test
drivers already present in the kernel also use exported symbols too, so
I see nothing new here.
