Mark DEVICE_ATTR_RO(name) in CACHE_ATTR(name, fmt)'s definition as static to fix
the following Sparse tool reports:

drivers/base/node.c:239:1: warning:
 symbol 'dev_attr_line_size' was not declared. Should it be static?
drivers/base/node.c:240:1: warning:
 symbol 'dev_attr_indexing' was not declared. Should it be static?

Where dev_attr_{line_size,indexing} are generated by CACHE_ATTR's expansion.
