Merge tag 'drm-misc-next-2018-11-28' of git://anongit.freedesktop.org/drm/drm-misc into drm-next
drm-misc-next for v4.21: 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:
-* 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.
+Remove custom dumb_map_offset implementations
+---------------------------------------------
-This way drivers/patches in the progress of getting merged won't break.
+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+implementation (there's lots of outdated locking leftovers in various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.
