[PATCH] drm/amdgpu: fix uvd crash on Polaris12 during driver unloading

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

 



There was a change(below) target for such issue:
cdccf1ffe1a3 drm/amdgpu: Fix crash on device remove/driver unload
But the fix for VI ASICs was missing there. This is a supplement for
that.
