New one introduced small letter at begin of sentence, so imho
old one was correct here.

imho old description is also good, all igt code is "testing something"
so maybe shorten this (?) like:
igt_describe("Simple checks of FB_DAMAGE_CLIPS plane property");
Maybe you want to keep it consistent with other descriptions ? Then it
may go with your change here like:
igt_describe("Test FB_DAMAGE_CLIPS plane property");
or
igt_describe("Use FB_DAMAGE_CLIPS plane property");
> + igt_subtest("atomic-plane-damage") {
-------------------- ^
This changes test name, it is not cosmetic one.
