From 943b33564e78130014ca91b575181becc828179e Mon Sep 17 00:00:00 2001 From: Richard Weinberger Date: Mon, 6 Oct 2014 14:57:18 +0200 Subject: [PATCH] UBI: Fastmap: Notify user in case of an ubi_update_fastmap() failure If ubi_update_fastmap() fails notify the user. This is not a hard error as ubi_update_fastmap() makes sure that upon failure the current on-flash fastmap will no be used upon next UBI attach.
