Subject: [PATCH v1] powerpc/process: Remove unnecessary #ifdef
 CONFIG_FUNCTION_GRAPH_TRACER
To:     Benjamin Herrenschmidt <benh@kernel.crashing.org>,
        Paul Mackerras <paulus@samba.org>,
        Michael Ellerman <mpe@ellerman.id.au>

Date:   Mon, 17 Aug 2020 05:46:39 +0000 (UTC)
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

ftrace_graph_ret_addr() is always defined and returns 'ip' when
CONFIG_FUNCTION GRAPH_TRACER is not set.

So the #ifdef is not needed, remove it.
