Good try :) That should be "From: ..."
git format-patch/send-email will handle this automatically if the commit
author is set correctly, ie:
git commit --amend --author="Andrew Donnellan
<andrew.donnel...@au1.ibm.com>"
The configuration space for opencapi devices doesn't have a PCI
Express capability, therefore confusing linux in thinking it's of an
old PCI type with a 256-byte configuration space size, instead of the
desired 4k. So add a PCI fixup to declare the correct size.
