From 94d010a7b2d46f79be1b805ece7ecd7d6188cdb3 Mon Sep 17 00:00:00 2001
From: Arnd Bergmann <arnd@arndb.de>

Subject: [PATCH 3891/4256] drm/amd/display: hide an unused variable
Without CONFIG_DEBUG_FS, we get a warning for an unused
variable:
drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:6020:33: error: unused variable 'source' [-Werror,-Wunused-variable]
Hide the variable in an #ifdef like its only users.
Fixes: 14b2584636c6 ("drm/amd/display: add functionality to grab DPRX CRC entries.")
