From 4b3e0a25aa5518892ec8dbfafdd6a57789aa0c22 Mon Sep 17 00:00:00 2001 From: Richard Weinberger Date: Sat, 28 Sep 2013 15:55:12 +0200 Subject: UBI: Call scan_all() with correct offset in error case If we find an invalid fastmap we have to scan from the very beginning. Otherwise we leak the first 64 PEBs.
