From 2abc52d6d911ec52da9b7d50f7ef09ef63854a08 Mon Sep 17 00:00:00 2001

Subject: [PATCH 0367/1110] drm/amd/amdgpu: Make afmt_init() cleanup if alloc
fails (DCEv11)
Updated DCEv11 afmt_init to cleanup if any kzalloc
fails and then return an error code. Don't continue initializing
the audio stack in that case.
