3.2.76-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Clemens Ladisch <clemens@xxxxxxxxxx>
commit bf1d1c9b6179faa3bc32cee882462bc8eebde25d upstream.
Add a DECLARE_TLV_DB_RANGE() macro so that dB range information
can be specified without having to count the items manually for
TLV_DB_RANGE_HEAD().
