Subject: [PATCH 14/60] mtd: m25p80: set writebufsize
commit b54f47c8bcfc5f766bf13ec31bd7dd1d4726d33b upstream.
Using UBI on m25p80 can give messages like:
UBI error: io_init: bad write buffer size 0 for 1 min. I/O unit
We need to initialize writebufsize; I think "page_size" is the correct
"bufsize", although I'm not sure. Comments?
