Also remove the now no longer needed build bug on since that's already
not needed anymore with drmm_add_final_kfree. Conversion to managed
drm_device cleanup is easy, the final drm_dev_put() is already the
last thing in both the bind unbind as in the unbind flow.
Also, this relies on component.c correctly wrapping bind&unbind in
separate devres groups, which it does.

The Documentation/DMA-API-HOWTO.txt states that the dma_map_sg() function
returns the number of the created entries in the DMA address space.
However the subsequent calls to the dma_sync_sg_for_{device,cpu}() and
dma_unmap_sg must be called with the original number of the entries
passed to the dma_map_sg().
struct sg_table is a common structure used for describing a non-contiguous
memory buffer, used commonly in the DRM and graphics subsystems. It
consists of a scatterlist with memory pages and DMA addresses (sgl entry),
as well as the number of scatterlist entries: CPU pages (orig_nents entry)
and DMA mapped pages (nents entry).
It turned out that it was a common mistake to misuse nents and orig_nents
entries, calling DMA-mapping functions with a wrong number of entries or
ignoring the number of mapped entries returned by the dma_map_sg()
function.
To avoid such issues, lets use a common dma-mapping wrappers operating
directly on the struct sg_table objects and use scatterlist page
iterators where possible. This, almost always, hides references to the
nents and orig_nents entries, making the code robust, easier to follow
and copy/paste safe.

- drm_pci* are now legacy
- introduced managed DRM resources
- subclassing support for drm_framebuffer
- simple encoder helper
- edid improvements
- vblank + writeback documentation improved
- drm/mm - optimise tree searches
- port drivers to use devm_drm_dev_alloc
dma-buf:
- add flag for p2p buffer support
mst:
- ACT timeout improvements
- remove drm_dp_mst_has_audio

Spelling out _unlocked for each and every driver is a annoying.
Especially if we consider how many drivers, do not know (or need to)
about the horror stories involving struct_mutex.
Just drop the suffix. It makes the API cleaner.
Done via the following script:
__from=drm_gem_object_put_unlocked
__to=drm_gem_object_put
for __file in $(git grep --name-only $__from); do
sed -i "s/$__from/$__to/g" $__file;
done

drm_fb_helper_{add,remove}_one_connector() and
drm_fb_helper_single_add_all_connectors() are dummy functions now
and serve no purpose. Hence remove their calls.
This is the preparatory step for removing the
drm_fb_helper_{add,remove}_one_connector() functions from
drm_fb_helper.h
This removal is done using below sementic patch and unused variable
compilation warnings are fixed manually.

The max connector argument for drm_fb_helper_init() isn't used anymore
hence remove it.
All the drm_fb_helper_init() calls are modified with below sementic
patch.

Now that the fbops member of struct fb_info is const, we can start
making the ops const as well.
