+Subject: [PATCH 1674/2940] drm/amd/display: Fix "dc has no member named dml"
+ compile error
+
+For DCN disabled builds, dc->dml is stripped out. Therefore, guard usage
+in dc_create_state() with CONFIG_DRM_AMD_DC_DCN1_0.
+
+It fixes the following error:
+
+drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc.c: In function 'dc_create_state':
+>> drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc.c:1237:34: error: 'struct dc' has no member named 'dml'
+     memcpy(&context->bw_ctx.dml, &dc->dml, sizeof(struct display_mode_lib));
+                                     ^~
