Hi Dave,
Today's linux-next merge of the drm tree got a conflict in
drivers/gpu/drm/radeon/evergreen.c between commit 77e00f2ea94a
("drm/radeon/kms: bail on BTC parts if MC ucode is missing") from Linus'
tree and commit b15ba51207e5 ("drm/radeon: introduce a sub allocator and
convert ib pool to it v4") from the drm tree.
I think it is just context changes. I fixed it up (see below) and can
carry the fix as necessary.
