[PATCH 5.17 0364/1126] ASoC: codecs: wcd934x: fix return value of wcd934x_rx_hph_mode_put

[Greg Kroah-Hartman]

From: Srinivas Kandagatla <srinivas.kandagatla@xxxxxxxxxx>

[ Upstream commit 4b0bec6088588a120d33db85b1f0d9f096d1df71 ]

wcd934x_rx_hph_mode_put currently returns zero eventhough it changes the value.
Fix this, so that change notifications are sent correctly.
