Sorry for the late reply. For some reason mail ended up in spam folder which I noticed now.
I should have watched the device naming series.
My fix went to for-rc and I guess it wasn't applied to for-next which resulted into this merge conflict.
My understanding is, maintainers usually try to avoid merge conflict between for-next and for-rc branches before sending pull request from rdma tree.
I will try to be more careful in future to notify maintainer about it.
Your changes below looks good. Thanks.
