You are correct (although curiously the error from patch this time is a much cleaner
fail than before where it was detecting a repeated apply - ah well).
Could you rebase this series against staging/staging-next
from git.kernel.org please.  I'm far more likely to get something wrong doing
this than you are. Also you have the ability to test the result!

Sorry for the extra work but it's good to see lots of simultaneous interest
in this driver!

Thanks,

Jonathan
