drivers/ieee1394/raw1394.c:spinlock_t host_info_lock = SPIN_LOCK_UNLOCKED;
drivers/ieee1394/nodemgr.c:spinlock_t host_info_lock = SPIN_LOCK_UNLOCKED;

when both raw1394 and nodemgr are linked into vmlinux, it gets

drivers/ieee1394/raw1394.o(.data+0x8): multiple definition of `host_info_lock'
drivers/ieee1394/ieee1394.o(.data+0x8c): first defined here

Either host_info_lock should be static or it should be defined as
extern in one source and referenced in the others.
