+Subject: [PATCH 4672/5725] drm/amdgpu: Add amdgpu_atpx_get_dhandle()
+
+Since it seems that some vendors are storing the ATIF ACPI methods under
+the same handle that ATPX lives under instead of the device's own
+handle, we're going to need to be able to retrieve this handle later so
+we can probe for ATIF there.
