drm-misc-next for v4.21:

Browse source 
Core Changes:
 - Merge drm_info.c into drm_debugfs.c
 - Complete the fake drm_crtc_commit's hw_done/flip_done sooner.
 - Remove deprecated drm_obj_ref/unref functions. All drivers use get/put now.
 - Decrease stack use of drm_gem_prime_mmap.
 - Improve documentation for dumb callbacks.
 
 Driver Changes:
 - Add edid support to virtio.
 - Wait on implicit fence in meson and sun4i.
 - Add support for BGRX8888 to sun4i.
 - Preparation patches for sun4i driver to start supporting linear and tiled YUV formats.
 - Add support for HDMI 1.4 4k modes to meson, and support for VIC alternate timings.
 - Drop custom dumb_map in vkms.
 - Small fixes and cleanups to v3d.

Switch from reference/unreference to get/put
--------------------------------------------
For some reason DRM core uses ``reference``/``unreference`` suffixes for
refcounting functions, but kernel uses ``get``/``put`` (e.g.
``kref_get``/``put()``). It would be good to switch over for consistency, and
it's shorter. Needs to be done in 3 steps for each pair of functions:
Remove custom dumb_map_offset implementations
---------------------------------------------
* Create new ``get``/``put`` functions, define the old names as compatibility
wrappers
* Switch over each file/driver using a cocci-generated spatch.
* Once all users of the old names are gone, remove them.
All GEM based drivers should be using drm_gem_create_mmap_offset() instead.
Audit each individual driver, make sure it'll work with the generic
implementation (there's lots of outdated locking leftovers in various
implementations), and then remove it.
This way drivers/patches in the progress of getting merged won't break.
