Subject: [PATCH v2 13/41] drm/client: Add some tests for drm_connector_pick_cmdline_mode()
drm_connector_pick_cmdline_mode() is in charge of finding a proper
drm_display_mode from the definition we got in the video= command line
argument.
Let's add some unit tests to make sure we're not getting any regressions
there.
