smatch reports
sound/pci/emu10k1/emumixer.c:519:39: warning: symbol
  'emu1010_routing_info' was not declared. Should it be static?
sound/pci/emu10k1/emumixer.c:859:36: warning: symbol
  'emu1010_pads_info' was not declared. Should it be static?

These variables are only used in their defining file, so it should be static
