From b54f47c8bcfc5f766bf13ec31bd7dd1d4726d33b Mon Sep 17 00:00:00 2001 From: Brian Norris Date: Tue, 31 Jan 2012 00:06:03 -0800 Subject: [PATCH] mtd: m25p80: set writebufsize 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?
