Subject: [PATCH] ASoC: cs42xx8: Only define cs42xx8_of_match once
cs42xx8.c exports cs42xx8_of_match, so there's no need to redefine it
in cs42xx8-i2c.c - doing so breaks linking when loadable module
support is disabled. It would be tidy to use the exported match table
in cs42xx8.c's of_match_table member, but an imported symbol can't be
used in a module's MODULE_DEVICE_TABLE declaration. Instead, rename
the duplicated declarations so as not to clash.
