Here is the patch:
https://github.com/stefanha/linux/commit/a6d06644e3a58e57a774e77d7dc34c4a5a2e7496

Or as an email if you want to track it down in your inbox:

The code you posted is equivalent, the only additional thing my patch
did was to update doc comments in include/linux/virtio.h. Feel free to
grab my patch or just the hunk.
