DECLARE_TLV_DB_RANGE() has the advantage over using TLV_DB_RANGE_HEAD() that it automatically calculates the number of items in the TLV and is hence less prone to manual error.
Generate using the following coccinelle script
// <smpl> @@ declarer name DECLARE_TLV_DB_RANGE; identifier tlv; constant x; @@ -unsigned int tlv[] = { - TLV_DB_RANGE_HEAD(x), +DECLARE_TLV_DB_RANGE(tlv, ... -}; +); // </smpl>
