commit 54d217406a upstream.
I've been experiencing some intermittent crashes down in the display
driver code. The symptoms are ususally a line like this in dmesg:
amdgpu 0000:30:00.0: [drm] Failed to create MST payload for port 000000006d3a3885: -5
...followed by an Oops due to a NULL pointer dereference.
Switch to using mgr->dev instead of state->dev since "state" can be
NULL in some cases.
