(does a powerpc allmodconfig)

drivers/serial/nwpserial.c:443: warning: data definition has no type or storage class
drivers/serial/nwpserial.c:443: warning: type defaults to 'int' in declaration of 'console_initcall'
drivers/serial/nwpserial.c:443: warning: parameter names (without types) in function declaration
drivers/serial/nwpserial.c:400: warning: 'nwpserial_console_init' defined but not used

The file fails to include linux/init.h.  It should do so, but that
doesn't fix the above.

Apparently it hasn't been tested as a kernel module...

Console support doesn't work when the driver is build as module, all
other serial drivers did this with a further configuration option. Will
send an updated patch which fixes this and the other issues.
