I had expected that I would merge it into the asm-generic tree first and did not bother sending a separate Reviewed-by tag, but I agree that it's best if you create the branch. Can you add 'Reviewed-by: Arnd Bergmann ' to each patch and send me a pull request for a v5 tag so we can merge that into both the riscv and the asm-generic trees? Arnd
