This test, and the similar one in yaffs_search_advance, are not needed.
There is no way that sc can be passed as NULL here. Even if that could
happen you probably want to oops rather than silently carrying on.

I think there are similar issues in other functions throughout the yaffs
code where you are testing if various pointers are NULL and returning
silently if they are. All of these cases should be fixed to remove the
extraneous code.
