Thanks for the update. In the current form, it's not reviewable, or
trackable in patchwork
(https://patchwork.freedesktop.org/project/dri-devel/series/).
For sending patch series, please use 'git send-email' with the
--cover-letter option. This will provide you with a single email for
describing the patchset as a whole, and create all actual patch mails as
replies to the cover letter.
Maybe test this first with your local email account and then please
resubmit to the mailing list.
Best regards
Thomas
