[alsa-devel] [PATCH 37/42] ASoC: wm8991: Don't use range container for TLVs with one entry

[Lars-Peter Clausen]

For TLVs with only a single entry it is not necessary to use a range
container. Use DECLARE_TLV_DB_LINEAR() directly instead of a combination of
TLV_DB_RANGE_HEAD() and TLV_DB_LINEAR_ITEM().
