Subject: [PATCH] drm/amdgpu: move the amdgpu_fbdev_set_suspend() further up
Date: Tue, 24 Jul 2018 09:32:40 +0530	[thread overview]
Message-ID: <1532404960-2179-1-git-send-email-shirish.s@amd.com> (raw)

This patch moves amdgpu_fbdev_set_suspend() to the beginning
of suspend sequence.

This is to ensure fbcon does not to write to the VRAM
after GPU is powerd down.
