Subject: [PATCH] drm/amdgpu: update the domain flags for dumb buffer creation
After switching to generic framebuffer framework, we rely on the
->dumb_create routine for frame buffer creation. However, the
different domain flags used are not optimal. Add the contiguous flag to directly allocate the scanout BO as one linear buffer.
Fixes: 844612e1149d ("drm/amdgpu: use generic fb helpers instead of setting up AMD own's.")
