SubjectRe: [Intel-gfx] [PATCH] dma-buf: Rename dma-ops to prevent conflict with kunmap_atomic macro
Hi Logan,

[auto build test ERROR on linus/master]
[also build test ERROR on v4.11-rc7 next-20170418]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

url: https://github.com/0day-ci/linux/commits/Logan-Gunthorpe/dma-buf-Rename-dma-ops-to-prevent-conflict-with-kunmap_atomic-macro/20170419-082521
config: arm64-defconfig (attached as .config)
