Subject: ASoC: Fix return value of ak4641_pcm_set_dai_fmt()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=16aff769d73c6b66a79450d7218f31dc46962536;p=openwrt%2Fstaging%2Fblogic.git

ASoC: Fix return value of ak4641_pcm_set_dai_fmt()

We can't just pass back the return value of snd_soc_update_bits() as it
will be 1 if a bit changed rather than zero.
