Please split your patch on pmag-ba-fb and pmagb-b-fb
parts and fix patch subjects while at it ("video: fbdev:
pmag-ba-fb: remove incorrect __exit markup" and "video:
fbdev: pmagb-b-fb: remove incorrect __exit markup").

'__init' annotations have already been fixed by Maciej
(patches are in fbdev-for-next branch of my tree) so
please drop these changes from your patches.
