From 1760bd06c8e94e1b184139ae35201856403638cf Mon Sep 17 00:00:00 2001 From: Wesley Chalmers Date: Thu, 23 May 2019 11:54:12 -0400 Subject: [PATCH] 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.
