Suddenly everyone shows up with their trivial patch series!
- piles of if (!ptr) check removals from Markus Elfring
- more of_node_put fixes from Peter Chen
- make fbdev support really optional in all drivers (except vmwgfx),
somehow this fell through the cracks when we did all the hard prep work
a while ago. Patches from Tobias Jakobi.
- leftover patches for the connector reg/unreg cleanup (required that I
backmerged drm-next) from Chris
- last vgem fence patch from Chris
- fix up warnings in the new sphinx gpu docs build
- misc other small bits

Backmerge tag 'v4.7' into drm-next
Linux 4.7
As requested by Daniel Vetter as the conflicts were getting messy.
of_node_put needs to be called when the device node which is got
from of_parse_phandle has finished using.

Back-merge tag 'v4.7-rc5' into drm-next
Linux 4.7-rc5
The fsl-dcu pull needs -rc3 so go to -rc5 for now.
The sun4i display engine doesn't have any vblank counter. Use the proper
helper for that.

Date: Fri Dec 11 11:20:28 2015 +0100
drm: use dev_name as default unique name in drm_dev_alloc()
we're using a reasonable default which should work for everyone. Only
mtk, rcar-du and sun4i are affected, and as kms-only drivers without
any rendering support no one should ever care about the unique name
v2: Rebase on top of mediatek.

If simplefb was setup by our bootloader and enabled in the DT, we will have
a first framebuffer loaded in our system.
However, as soon as our DRM driver will load, it will reset the controller,
initialise it and, if the framebuffer emulation is enabled, register a
second framebuffer device.
This is obviously pretty bad, since the first framebuffer will be some kind
of a black hole, with memory still reserved that we can write to safely,
but not displayed anywhere.
Make sure we remove that framebuffer when we probe so we don't end up in
that situation.

One of the A10 display pipeline possible output is an RGB interface to
drive LCD panels directly. This is done through the first channel of the
TCON that will output our video signals directly.

The Allwinner A10 and subsequent SoCs share the same display pipeline, with
variations in the number of controllers (1 or 2), or the presence or not of
some output (HDMI, TV, VGA) or not.
Add a driver with a limited set of features for now, and we will hopefully
support all of them eventually
