The struct drm_dp_desc contains struct drm_dp_dpcd_ident, and the struct
drm_dp_dpcd_ident contains the array, so zero-initialization requires a
more couple of braces. In the ARM compiler environment, the compile
warning pointing it out:
drivers/gpu/drm/drm_dp_mst_topology.c: In function
'drm_dp_mst_dsc_aux_for_port':
drivers/gpu/drm/drm_dp_mst_topology.c:5494:9: warning: missing braces
around initializer [-Wmissing-braces]
struct drm_dp_desc desc = { 0 };
