Florian Westphal 6a13f5afd3 xfrm: policy: fix null dereference
Julian Wiedmann says:
> +     if (!xfrm_pol_hold_rcu(ret))

Coverity spotted that ^^^ needs a s/ret/pol fix-up:

> CID 1599386:  Null pointer dereferences  (FORWARD_NULL)
> Passing null pointer "ret" to "xfrm_pol_hold_rcu", which dereferences it.

Ditch the bogus 'ret' variable.

Fixes: 563d5ca93e ("xfrm: switch migrate to xfrm_policy_lookup_bytype")

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
