I think this is a valid concern. In theory, the NAND infrustructure must
guarantee that the buffer is always of even length, and most probably it
does, but we could add a WARN_ON(len & 1) statements in
'atmel_read_buf()' and 'atmel_write_buf()'.

And probably the type could indeed be changed.

But these concerns should be addressed separately.
