mips: make loongsoon serial driver explicitly modular
The file looks as if it is non-modular, but it piggy-backs off CONFIG_SERIAL_8250 which is tristate. If set to "=m" we will get this after the init/module header cleanup: arch/mips/loongson/common/serial.c:76:1: error: data definition has no type or storage class [-Werror] arch/mips/loongson/common/serial.c:76:1: error: type defaults to 'int' in declaration of 'device_initcall' [-Werror=implicit-int] arch/mips/loongson/common/serial.c:76:1: error: parameter names (without types) in function declaration [-Werror] arch/mips/loongson/common/serial.c:58:19: error: 'serial_init' defined but not used [-Werror=unused-function] cc1: all warnings being treated as errors make[3]: *** [arch/mips/loongson/common/serial.o] Error 1 Make it clearly modular, and add a module_exit function, so that we avoid the above breakage.
