Bug description:
=== SRU Justification===
[Impact]
On new amdgpu ARCTURUS and RENOIR, system got call trace and hang
because of some acpi events.
[Fix]
This is a kernel NULL pointer bug.
Check for NULL pointers before calling.
[Test]
Verified on hw, amdgpu works fine.
[Regression Potential]
Low, it's safe to check NULL pointers.
This new amdgpu is supported since 5.4, no need for lower version
kernel.
