Hi Dave,
Today's linux-next merge of the drm tree got a conflict in
drivers/gpu/drm/radeon/radeon_kfd.c between commit b64b8afcca9d
("drm/amd: Fixing typos in kfd<->kgd interface") from Linus' tree and
commit a84a9903b588 ("drm/radeon: Implement SDMA interface functions")
from the drm tree.
I fixed it up (see below) and can carry the fix as necessary (no action
is required).
