From 64f60710568db5cec1a76c1d1e261b239f9ef809 Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Tue, 30 Jan 2007 10:50:43 +0200 Subject: [MTD] remove unused ecctype,eccsize fields from struct mtd_info Remove unused and broken mtd->ecctype and mtd->eccsize fields from struct mtd_info. Do not remove them from userspace API data structures (don't want to breake userspace) but mark them as obsolete by a comment. Any userspace program which uses them should be half-broken anyway, so this is more about saving data structure size.
