Subject: [PATCH 1/2] drm/amd/powerplay: refine code in cz_smumgr.c
Date: Fri, 23 Dec 2016 17:50:00 +0800	[thread overview]
Message-ID: <1482486601-4681-1-git-send-email-Rex.Zhu@amd.com> (raw)

cz_smu_init will be called in sw_init.
so it should not touch other blocks's
firmware as they were not ready.
