DAL warnings during driver unbind

Harry, with DAL enabled I observe warnings and unbind can't complete - 
to reproduce under root do 

cd /sys/bus/pci/drivers/amdgpu/
echo 'pci_id' > unbind where pci_id is seen when doing ls -l on this folder and
seeing soft link like this 
0000:2a:00.0 -> ../../../../devices/pci0000:00/0000:00:03.1/0000:2a:00.0/
