Hello Bilal,
Please find comments inline.
Fix commit message on both as it seems interchanged.

Name your connector_test macro to connector_subtest("dp-hpd", DisplayPort)
Patch 1
introduce connector_test
Patch 2
Replace all calls to connector_subtest with your connector_test,
including (audio, frames, edid)
Patch 3
Remove connector_subtest, rename connector_test -> connector_subtest and
rename all calls
Thanks and Regards
