Merge tag 'ntb-bugfixes-3.10' of git://github.com/jonmason/ntb
Pull NTB update from Jon Mason:
"NTB bug fixes to address Smatch/Coverity errors, link toggling bugs,
and a few corner cases in the driver."
This pull request came in during the merge window, but without any
signage etc. So I'm taking it late, because it wasn't _originally_
late.
