[PATCH 2/4] include/linux/ascii85: Update ascii85_encode()

[Sharat Masetty]

The current implementation of ascii85_encode() does not copy the encoded
buffer 'z' to the output buffer in case the input is zero. This patch
simply adds this missing piece. This makes it easier to use this
function to encode large buffers.
