gpio-patchset-fixups: series

hi Andrew,

heres that pile of tiny patches..

It seems that a lot of the externs you noted were fixed in subsequent patches. The other fixups should work for your 'insertion sort'.
Sorry about these faux-pas, I'll do better next time.

They apply cleanly on mm1, and build fine.
Sadly, I cant boot -mm1 ATM (some nfsroot prob I'll try to dig into RSN), so I tested against 17, theyre fine there.
