Subject: ASoC: cs42l73: Fix clear wrong bits in cs42l73_set_dai_fmt
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7b282cbbf3c7bbad20505761a9eadd6d9a7280c7;p=linux-beck.git

ASoC: cs42l73: Fix clear wrong bits in cs42l73_set_dai_fmt

What we want is to clear BIT[5:4](PCM_MODE_MASK) and BIT[3](PCM_BIT_ORDER) bits,
but current code clears BIT[2:0].
