Andrew, please don't blindly apply Coverity patches. While the checker
is smart at finding inconsistencies, that "obvious" fix is wrong most of
the item. As in this unreviewed UDF patch that got in:
udf_find_entry can never be called with a NULL argument, so we shouldn't
check for it instead of adding more assignments behind the check.
