Thanks for your feedback!

You need to apply this patch 
https://gitlab.freedesktop.org/ArvindYadav/drm-next/-/commit/cc6dcff192d07f9fe82645fbc4213c97e872156b

This patch adds the file drivers/gpu/drm/ci/gitlab-ci.yml for you.

And you can drop the patch where gitlab added the ci template.

I replied here too 
https://gitlab.freedesktop.org/ArvindYadav/drm-next/-/commit/cc6dcff192d07f9fe82645fbc4213c97e872156b

Could you try again with that patch?

Thanks a lot!
Helen
