[igt-dev] [PATCH i-g-t 2/2] kunit tests: add an optional name for the selftests

[Mauro Carvalho Chehab]

From: Mauro Carvalho Chehab <mchehab at kernel.org>

When multiple KUnit tests are called by the same program, it is
interesting to group them with a name. This would allow IGT
namespace to better refer to the KUnit tests and will give some
filtering capability to it.

After those changes, the IGT kUnit tests will be better named:

	$ for i in kms_selftest drm_buddy drm_mm; do echo $i:; build/tests/$i --list; echo; done
	kms_selftest:
	drm_cmdline
	drm_damage
	drm_dp_mst
	drm_format_helper
	drm_format
	framebuffer
	drm_plane
	all-tests

	drm_buddy:
	all-tests

	drm_mm:
	all-tests
