[PATCH] drm/amdgpu: remove gart.ready flag
Christian König

Tue Jan 18 12:01:57 UTC 2022
That's just a leftover from old radeon days and was preventing CS and GART
bindings before the hardware was initialized. But nowdays that is
perfectly valid.
The only thing we need to warn about are GART binding before the table
is even allocated.
