Maybe it was used more widely previously?
The only place that I found it in use was amdgpu_device_evict_resources.

[AMD Official Use Only]
I don't think this will work properly. The in_s3 flag was mainly for runtime pm vs system suspend. I'm not sure if in_s0ix is properly handled everywhere we check in_s3.
This makes it clearer which codepaths are in use specifically in
one state or the other.
