[ 119/120] udf: fix retun value on error path in udf_load_logicalvol

From: Greg Kroah-Hartman
Date: Wed Oct 10 2012 - 21:15:14 EST


3.4-stable review patch. If anyone has any objections, please let me know.

------------------

From: Nikola Pajkovsky <npajkovs@xxxxxxxxxx>

commit 68766a2edcd5cd744262a70a2f67a320ac944760 upstream.

In case we detect a problem and bail out, we fail to set "ret" to a
nonzero value, and udf_load_logicalvol will mistakenly report success.
