Cannot compile latest mtd with 2.6.10

[Mandeep Ahuja <ahuja@aksysnetworks.com>]

Hi,
I recently check out the 'mtd' module from CVS. I have kernel 2.6.10 for 
mips malta board. I ran the patchkernel.sh script and then tried to 
compile my kernel.

I ran into this
 CHK     include/linux/version.h
make[1]: `arch/mips/kernel/offset.s' is up to date.
 CHK     include/asm-mips/offset.h
 CHK     include/linux/compile.h
 CHK     usr/initramfs_list
 CC      drivers/mtd/mtdcore.o

of `DEFINE_MUTEX'

function declaration

storage class

in a function)

`mutex_lock'

`mutex_unlock'
drivers/mtd/mtdcore.c: At top level:

section type conflict
make[2]: *** [drivers/mtd/mtdcore.o] Error 1
make[1]: *** [drivers/mtd] Error 2
make: *** [drivers] Error 2

Looks like some mutex problem, but the 2.6.10 does not have mutexes. How 
do I get around this problem?

Would appreciate any help
thanks
