[alsa-devel] [PATCH 1/4] ALSA: control: complement TLV macro for db-minmax and db-linear types

[Takashi Sakamoto]

A commit 08f9f4485f21 ('ALSA: core api: define offsets for TLV items')
introduced a series of macro for offset of db-scale type of TLV, however
there are some types of TLV to add similar macros.

This commit complements macros for offset of db-minmax and db-linear types
of TLV data.
