[PATCH 12/35] UBI: Fastmap: Notify user in case of an ubi_update_fastmap() failure

From: Richard Weinberger
Date: Wed Oct 29 2014 - 08:53:55 EST


If ubi_update_fastmap() fails notify the user.
This is not a hard error as ubi_update_fastmap() makes sure upon failure that
the current on-flash fastmap will no be used upon next UBI attach.
