Hi Dan,

Thank you for the feedback - reason I removed the padapter arg is
because I was the one that added it. To be clear, you're happy with this
and the brace changes etc. as long as I take them out within a separate
patch at the end of the series?

I had quite a few unused variable errors along the way, but evidently
with the way my build system is setup it doesn't currently show set but
unused variables. I will fix this and deal with the kernel test robot
warnings. Many thanks.

Regards,
Phil
