locking related bug detected since "drm/amdgpu: lookup vbios table to check ecc capability"

[Michel Dänzer]

Hi Xinhui,


since this commit, amdgpu_ras_init runs on my development system with
Bonaire, and generates the attached BUG and lock debug warning reports.


Before this commit, amdgpu_ras_init returned early, because RAS isn't
supported. There's no mention of this change of behaviour in the commit
log, and it doesn't seem related to checking a VBIOS table for ECC
capability. Was it intended?


P.S. AFAICT this patch wasn't submitted to the amd-gfx list for review.
All changes must be reviewed here before being applied to
amd-staging-drm-next.
