First, sorry for creating an issue about a meta topic, but I really can't figure out the intended workflow for contribution here.
I wanted to submit a patch that changes the package url from the upstream kernel url to this repository's location so that it's easier to contribute to and see history of the additional patches and kernel config used.
I couldn't edit the PKGBUILD with the web UI (it suggested to fork and submit a subsequent MR), so I clicked the presented fork button, only to receive the following error:
Fork Error! You tried to fork manjaro-arm / packages / core / linux-pinephone but it failed for the following reason: – Namespace is not valid
So I tried to clone the project to gitlab.com and work there, then submit a MR back to Manjaro's gitlab.
The first half of this plan went fine (https://gitlab.com/aaaz/linux-pinephone), but I can't find a way to submit a merge request on this repository.
Sorry for the trouble, and thanks for your help.
