[igt-dev] [PATCH i-g-t 2/3] tests/kms_plane_lowres: Stop relying in debugfs display_info

From: Ville Syrjälä <ville.syrjala at linux.intel.com>
Switch the test to rely purely on crcs instead of parsing stuff
from the debugfs display_info file. Such parsin is fragile and
will cause test failures whenever anyone tries to adjust the
file layout. Let's trust that crcs are good enough to catch
cases where we misconfigure the planes.
