A simple off-by-one. The driver in question always sent one byte
too much which causes trouble if you accidentally write garbage to
your flash chip's second status register. Some chips enable write
protection that way and certain firmware doesn't work reliable any
more in that state :D

Don't ask me why it writes to the status register at all by default.
I don't remember.
