[Yaffs] Yaffs compilation error on linux 3.6.8 for arm

Hi All,

I recently changed the kernel for my arm9 based system from linux 2.6.21 to
linux 3.6.8. I then applied the patch as suggested in the Readme document.

now, when I select the YAFFS2 package with the kernel configuration and
compile I get the error message and I am not able to do any thing further.
