Subject[PATCH 4.19 44/51] drm/amdgpu: remove ATPX_DGPU_REQ_POWER_FOR_DISPLAYS check when hotplug-in
Date
From: Aaron Liu <aaron.liu@amd.com>

commit bdb1ccb080dafc1b4224873a5b759ff85a7d1c10 upstream.

In amdgpu_atif_handler, when hotplug event received, remove
ATPX_DGPU_REQ_POWER_FOR_DISPLAYS check. This bit's check will cause missing
system resume.
