This patch series addresses two flaws in mtdchar_write_ioctl() found by
Richard Weinberger while he was reviewing v3 of the patch series
proposing a new MEMREAD ioctl [1].

Richard, I included a Suggested-by tag crediting you in both of the
patches in this series. I hope that is okay with you, but please let me
know if it isn't.

Once this patch series is reviewed and accepted, I will apply similar
fixes in v4 of the MEMREAD ioctl patch series.
