ieee1394 does not compile

[root]

I have the following in my .config

#
# IEEE 1394 (FireWire) support (EXPERIMENTAL)
#
CONFIG_IEEE1394=y

#
# Device Drivers
#
# CONFIG_IEEE1394_PCILYNX is not set
CONFIG_IEEE1394_OHCI1394=y

#
# Protocol Drivers
#
CONFIG_IEEE1394_VIDEO1394=y
CONFIG_IEEE1394_SBP2=y
CONFIG_IEEE1394_RAWIO=y
# CONFIG_IEEE1394_VERBOSEDEBUG is not set

And I get the following message when make bzImage

ld -m elf_i386  -r -o ieee1394drv.o ieee1394.o ohci1394.o video1394.o raw1394.o sbp2.o
raw1394.o(.data+0x8): multiple definition of `host_info_lock'
ieee1394.o(.data+0x8c): first defined here
make[3]: *** [ieee1394drv.o] Error 1

make[1]: *** [_subdir_ieee1394] Error 2
make[1]: Leaving directory `/usr/src/linux/drivers'

After changing in raw1394.c:

spinlock_t host_info_lock = SPIN_LOCK_UNLOCKED;

into:

extern spinlock_t host_info_lock;

everything compiles fine!
