[PATCH 5.19 336/717] ASoC: codecs: tx-macro: fix kcontrol put

From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>

[ Upstream commit c1057a08af438e0cf5450c1d977a3011198ed2f8 ]

tx_macro_tx_mixer_put() and tx_macro_dec_mode_put() currently returns zero
eventhough it changes the value.
Fix this, so that change notifications are sent correctly.

Fixes: d207bdea0ca9 ("ASoC: codecs: lpass-tx-macro: add dapm widgets and route")
