drm/amd/display: implement dc_init_callbacks to assign callback pointers after dc_create (d5cf79ee) · Commits · 戴 / test

[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. Signed-off-by:
