Subject: [PATCH] mtd: fix reading data from page that needs cleanup
Date: Thu, 23 Mar 2017 14:20:07 +0100	[thread overview]
Message-ID: <20170323132007.26629-1-s.hauer@pengutronix.de> (raw)

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.
