Use

#define MODULE_GENERIC_STRING(name, string) \
static const char __module_generic_string_##name [] \
  __attribute__ ((section(".modstring"))) = #name "=" string;

instead. __module_generic_string_info_parm_snd_major[ is not a valid cpp
token and ISO C99 sais pasting which does not result in a valid
preprocessing token has undefined behaviour.
