From 66d7674f8babfebac46ee203f7d64deda0d7ab21 Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Mon, 20 Mar 2017 13:26:09 +0100 Subject: [PATCH] mtd: fix reading data from page that needs cleanup MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit mtd_read´() returns -EUCLEAN to indicate that a page needs cleanup. This value shouldn't be returned from the mtd read file operation since this should return the number of bytes read.
