This looks cleaner if you skip the unnecessary 0 entries
and also use additional {}.

static const struct tlv_proc tlv_default_proc = {
	.params.t = {
		.admin_perm = IPV6_TLV_PERM_NO_CHECK,
		.user_perm = IPV6_TLV_PERM_NONE,
		.align_mult = 3,  /* Default alignment: 4n + 2 */
		.align_off = 2,
		.max_data_len = 255,
	},
};
