libnvdimm: Fix compilation warnings with W=1
Several places (dimm_devs.c, core.c etc) include label.h but only label.c uses NSINDEX_SIGNATURE, so move its definition to label.c instead. In file included from drivers/nvdimm/dimm_devs.c:23: drivers/nvdimm/label.h:41:19: warning: 'NSINDEX_SIGNATURE' defined but not used [-Wunused-const-variable=] Also, some places abuse "/**" which is only reserved for the kernel-doc. drivers/nvdimm/bus.c:648: warning: cannot understand function prototype: 'struct attribute_group nd_device_attribute_group = ' drivers/nvdimm/bus.c:677: warning: cannot understand function prototype: 'struct attribute_group nd_numa_attribute_group = ' Those are just some member assignments for the "struct attribute_group" instances and it can't be expressed in the kernel-doc.
