linux-next: manual merge of the fbdev tree with the mm tree

Hi all,

Today's linux-next merge of the fbdev tree got a conflict in:

  drivers/video/fbdev/ssd1307fb.c

between commit:

  d4488917e79c7 ("fbdev: defio: assert FBINFO_VIRTFB, drop VM_IO, add VM_MIXEDMAP")

from the mm tree and commit:

  81ae1f9a6c850 ("fbdev: ssd1307fb: check for fb_deferred_io_init() error")

from the fbdev tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

Wow a conflict between two of my patches I have literally no excuses here :))
