Are you sure you want 'debug' in your boot arguments?
The rest lgtm. I can remove debug when applying, or leave it there if
it was intentional.

Ahh, I copied bootargs from "/proc/cmdline" on my machine (running old kernel) but I don't think I need it.
Thank you for pointing it out. Let me send out v2 patches in a few minutes (so you could apply without extra changes).
