radeon_connector_unregister NULL ptr deref

Hi guys,

I'm getting a NULL ptr deref splat when hibernating my box with
4.9-rc1+. All I got so far is an ugly camera shot from the splat which
I'm typing in by hand.

Any ideas or already a fix?

The callstack looks like this:

unable to handle kernel NULL pointer dereference at 00...0890 (I think it is 890)
IP: radeon_connector_unregister+0xc/0x40
...

? drm_connector_unregister.part
drm_connector_unregister_all
drm_modeset_unregister_all
drm_dev_unregister
drm_put_dev
radeon_pci_shutdown
pci_device_shutdown
device_shutdown
kernel_power_off
power_down
hibernate
...

Thanks.
