Subject: [PATCH] drm/amdgpu: fix dma mask check in gmc_v6_0.c
This got messed up by "drm: change func to better detect wether swiotlb
is needed".
Shoot, I thought I hunted all those down! Sorry about that.
Can I get an rb or ab so that I can push it directly after your change?
BTW: I pushed your change to drm-misc-next and its on it way to upstream.
Christian.
