Subject: [PATCH] ASoC: codecs: wcd934x: fix return value of wcd934x_rx_hph_mode_put
Git-commit: 4b0bec6088588a120d33db85b1f0d9f096d1df71
Patch-mainline: v5.18-rc1
References: git-fixes
wcd934x_rx_hph_mode_put currently returns zero eventhough it changes the value.
Fix this, so that change notifications are sent correctly.
Fixes: 1cde8b822332 ("ASoC: wcd934x: add basic controls")
