From 770c1ef83c2628cea4e9070810609b102037339a Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Mon, 31 Aug 2015 13:15:03 +0200 Subject: mtd: core: initialize *retlen in mtd_write() Some mtd drivers like the spi-nor driver do not assign a value to the retlen pointer but instead only add the bytes written to *retlen. Users of mtd_write expect the variable to be initialized by the mtd core though, so we have to do it in mtd_write(). The same is done in mtd_read already.
