+Subject: Revert "memory: fsl_ifc: fix leak of IO mapping on probe failure"
+
+From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
+
+This reverts commit b7a2bcb4a3731d68f938207f75ed3e1d41774510 which is
+commit 3b132ab67fc7a358fff35e808fa65d4bea452521 upstream.
+
+As reported, it breaks the build, the 'gregs' field is not in the 4.4.y
+kernel tree.
