From 85db25a85ec872408a3059a8559ca2b84556e261 Mon Sep 17 00:00:00 2001

Date: Sat, 22 Apr 2017 14:17:51 -0400
Subject: [PATCH 0376/4131] drm/amd/display: decouple resource_pool from
 resource_context

to avoid null access in case res_ctx is used to access res_pool before it's fully constructed

also make it clear which function has dependency on resource_pool
