[ 14/59] mtd: m25p80: set writebufsize

[Greg KH]

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Brian Norris <computersforpeace@xxxxxxxxx>

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?
