... and pushed, thanks!


Also please remember of setting subject prefix to "PATCH i-g-t" as it
makes the changes easily trackable via filters and patchwork :-)

Excerpt from CONTRIBUTING:
-----------------------------------------------------------------------------
Please use --subject-prefix="PATCH i-g-t" so that i-g-t patches are easily
identified in the massive amount mails on intel-gfx. To ensure this is always
done, autogen.sh will run:

  git config format.subjectprefix "PATCH i-g-t"

on its first invocation.
-----------------------------------------------------------------------------

The autogen.sh thing is new addition.
