ASoC: max9850: Replace TLV_DB_RANGE_HEAD with DECLARE_TLV_DB_RANGE
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> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>
