[Yaffs] Is there kernel patch

Hi,

   I am trying to port the YAFFS in my ARM platform.
I am using the 2.4.18 kernel version. I am getiing the compilation errors.
/usr/local/arm/2.95.3/bin/arm-linux-gcc -c -D__KERNEL__ -DMODULE 
-DCONFIG_YAFFS_RAM_ENABLED -DCONFIG_YAFFS_MTD_ENABLED
-DCONFIG_YAFFS_USE_GENERIC_RW    -DCONFIG_SHORT_NAMES_IN_RAM
-DCONFIG_YAFFS_USE_NANDECC    -I
/home/hariharan/CVS-PHONE/Software/Kernel/include -O2 -Wall
yaffs_mtdif.c -o yaffs_mtdif.o
yaffs_mtdif.c: In function `nandmtd_WriteChunkToNAND':
yaffs_mtdif.c:60: too many arguments to function
yaffs_mtdif.c:62: too many arguments to function
yaffs_mtdif.c: In function `nandmtd_ReadChunkFromNAND':
yaffs_mtdif.c:97: too many arguments to function
yaffs_mtdif.c:101: too many arguments to function
make: *** [yaffs_mtdif.o] Error 1

Is there any patch for kernel 2.4.18 kernel version
