Happy to apply this series via the PCI tree given an ack from Thomas.

In that event I would rewrap the commit logs to fit in 75 columns and
include a note in the driver patches about what event causes the
warning.  No need to repost for that unless other changes are needed.

Thanks for doing this work!
