Subject: udf: fix retun value on error path in udf_load_logicalvol
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=68766a2edcd5cd744262a70a2f67a320ac944760;p=linux-beck.git

udf: fix retun value on error path in udf_load_logicalvol

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.
