Subject: [PATCH] ALSA: emu10k1: set variables emu1010_routing_info and emu1010_pads_info storage-class-specifier to static

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

I have been running smatch against the whole tree for a while, using
this preamble.

Many fixes later, for the most part the tree has been cleaned of this
class of problems.

Note that smatch is a name of a static analysis tool :)
