In case a function argument is known/fixed size array in C, the argument is still decoyed as pointer instead ( T f(U n[k]) ~= T fn(U *n) ) and therefore calling sizeof on the function argument will result in the size of the pointer, not the size of the array.

The VFAT code contains such a bug, this patch fixes it.

I had the same problem with VFAT formatted USB stick on U-Boot 2013.01 as the original bug reported by Michail Simek. I have not made any deeper analysis of your patch, but it solved the problem.

Thanks! BR / Mats
