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)); ^~ Signed-off-by: Leo Li Acked-by: Alex Deucher Reviewed-by: Nicholas Kazlauskas Signed-off-by: Alex Deucher --- diff --git a/drivers/gpu/drm/amd/display/dc/core/dc.c b/drivers/gpu/drm/amd/display/dc/core/dc.c index 1c1cfb513620..5f05e191f0ff 100644 --- a/drivers/gpu/drm/amd/display/dc/core/dc.c +++ b/drivers/gpu/drm/amd/display/dc/core/dc.c @@ -1229,7 +1229,9 @@ struct dc_state *dc_create_state(struct dc *dc) * initialize and obtain IP and SOC the base DML instance from DC is * initially copied into every context */ +#ifdef CONFIG_DRM_AMD_DC_DCN1_0 memcpy(&context->bw_ctx.dml, &dc->dml, sizeof(struct display_mode_lib)); +#endif kref_init(&context->refcount);
