If you're ok > with that I can just fix up when applying. I put it here since regions never call __nd_device_register directly, they always call nd_device_register. I figured that by placing it here we reduce the impact of this on the other devices that aren't going to need it. _______________________________________________ Linux-nvdimm mailing list Linux-nvdimm@lists.01.org https://lists.01.org/mailman/listinfo/linux-nvdimm
