Subject: drm/amdgpu: move the amdgpu_fbdev_set_suspend() further up
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=5f8181733f6e5f8a4447f844efe4bdab5ed6a30e;p=openwrt%2Fstaging%2Fblogic.git

drm/amdgpu: move the amdgpu_fbdev_set_suspend() further up

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.
