From 3db980215dd1153ba0e77fd5aa06925254b15db4 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1004/2940] drm/amd/display: implement dc_init_callbacks to
assign callback pointers after dc_create
[why]
Some components depend on dc to constuct
but need to assign callback functions to dc.
[how]
Instead of assigning dc callback functions in dc_create,
decouple the callback init to a standlone function after dc_create. This
is currently a no-op.
