Currently we initialize nvdimm device like below: device_set_realized dc->realize nvdimm_plug nvdimm_build_fit_buffer acpi_build nvdimm_build_acpi This shows nvdimm's acpi stuff is prepared in two places: * device plug stage * acpi_build stage It would be more proper to build fit buffer in nvdimm_build_acpi, which consolidate all acpi related initialization together. This patch moves FIT build in nvdimm_build_acpi.
