From 3794943cb1026006db9363a3641973b62387e51a Mon Sep 17 00:00:00 2001 From: Sung Lee Date: Fri, 30 Aug 2019 13:36:40 -0400 Subject: [PATCH] drm/amd/display: add dummy functions to smu for Renoir Silicon Diags [Why] Previously only dummy functions were added in Diags for FPGA. On silicon, this would lead to a segmentation fault on silicon diags. [How] Check if diags silicon and if so, add dummy functions.
