You received comments already that you need to base your work on recent
Linux kernel and use scripts/ to notify necessary
parties. This is the fourth patchset and still you did not do it.

Maybe there is some misunderstanding or trouble using
scripts/, so could you clarify:

1. What is this based on? Output of: git describe

2. What does the scripts/ print when you run on this

Best regards,
