When converting the driver two arguments were transposed leading
to rfkill not working.

Looks like this broken in 4.14? So Cc stable back to then? I'm surprised it's
been broken that long :-(

Not many "newer" platforms actually use this radio control anymore.  It's been
superseded by other technologies.  So I think that would be the main reason.

Can you CC it to stable when it's committed or do I need to re-send or anything?

I will add the Cc to stable. Just wanted to confirm our expectations were
aligned.
