From 31f4f5970c6b6e5276a8ab7cc66e747bea98b799 Mon Sep 17 00:00:00 2001

Subject: [PATCH 4744/5725] drm/amd/display: Do not skip FBC init in failsafe
mode
Initially FBC would be initialized if display's edid was correct
and all the modes acquired from it, but n case when edid is corrupted
or non-existant we must still initialize FBC.
