From eadd1b0c65ded0401c3133349f8d049f9b9f7314 Mon Sep 17 00:00:00 2001
From: Wesley Chalmers <Wesley.Chalmers@amd.com>
Date: Thu, 23 May 2019 11:54:12 -0400
Subject: [PATCH 2073/2940] drm/amd/display: Use macro for invalid OPP ID
[WHY]
This is meant to make it clearer that 0xf is not a valid OPP ID, and
that code making use of OPP IDs should not accept this value.
