This patch and all the others in this series seem to be
missing your Signed-off-by: line.
(scripts/checkpatch.pl will catch this, among other things.)
Otherwise
Reviewed-by: Peter Maydell <address@hidden>
When you send out this patch in future versions of this series,
please include my Reviewed-by: tag in the commit message
after your signed-off-by line; that way I know I don't have
to recheck it. (If a patch changes much after somebody's
reviewed it you should drop the reviewed-by line and say why
in the cover letter.)
thanks
