+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.")
