[PATCH] drm/amdgpu: Fix uvd firmware version information for vega20

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The uvd version information was not set correctly for vega20.
Rearrange the logic to set it correctly and fix the warnings
as a result.

Fixes: 7b3c773f405 (drm/amdgpu/vg20:support new UVD FW version naming convention)

I'm not sure if this is exactly how we want to expose the new firmware versioning
to userspace, but it's better than random stack data.
