[PATCH 08/15] drm/amd/display: Move link_enc init logic to DC
Pavle Kotarac

Fri Dec 3 22:57:55 UTC 2021
From: Jude Shih <shenshih at amd.com>
[Why]
We shouldn't be accessing res_pool funcs from DM level,
therefore, we should create API and let the flow
be done in DC level.
[How]
We create new interface dp_get_link_enc to access and get the correct link_enc
