Subject: Applied "ASoC: msm8916-wcd-analog: Fix RX1 selection in RDAC2 MUX" to the asoc tree

The patch

   ASoC: msm8916-wcd-analog: Fix RX1 selection in RDAC2 MUX

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.4

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

Subject: [PATCH] ASoC: msm8916-wcd-analog: Fix RX1 selection in RDAC2 MUX

According to the PM8916 Hardware Register Description,
CDC_D_CDC_CONN_HPHR_DAC_CTL has only a single bit (RX_SEL)
to switch between RX1 (0) and RX2 (1). It is not possible to
disable it entirely to achieve the "ZERO" state.

However, at the moment the "RDAC2 MUX" mixer defines three possible
values ("ZERO", "RX2" and "RX1"). Setting the mixer to "ZERO"
actually configures it to RX1. Setting the mixer to "RX1" has
(seemingly) no effect.

Remove "ZERO" and replace it with "RX1" to fix this.
