Subject: drm/amdgpu: Remove duplicate setting of ->need_swiotlb
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=421334a8476fe53b147139e1221cf7b368dd7c6e;p=linux.git

drm/amdgpu: Remove duplicate setting of ->need_swiotlb

There's no need to set this before the number of DMA bits has been
properly determined.
