Subject: [PATCH 4.1 175/267] ima: cleanup ima_init_policy() a little

4.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <dan.carpenter@...cle.com>

commit 5577857f8e26e9027271f10daf96361640907300 upstream.

It's a bit easier to read this if we split it up into two for loops.
