Please send this as simple text mail, not a multi-part message with
attachments. I cannot comment inline for multi-part, not mentioning
that patch is not being displayed at all. Probably this is also the
reason why patch is not present in patchwork
(https://patchwork.kernel.org/project/linux-samsung-soc/list/).

The easiest is to just run "git format-patch -1" and then "git
send-email --to .. --cc .. 0001-*".

Best regards,
