Subject: drm/amdgpu: use direct loading on renoir vcn for the moment
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=444a0fea5107e9ad7e3cbbafed78678489e31713;p=linux.git

drm/amdgpu: use direct loading on renoir vcn for the moment

PSP has issue for renoir, that will cause VCN fw failed to be loaded. So use
direct loading for the moment till the issue is addressed.
