Don't know if you received the other fix, but 03de6b273805 broke
ipq806x. I already sent a fix for that but since it was added extra
check for crci, it seems logical that 03de6b273805 should have also
updated the nandc driver to handle the new pointer error. This was not
done so I added that fixes tag.

Tell me if the logic was wrong...
