Looks like we ended up with a typo during device tree data parsing
as part of 4f16b6351bbff ("ASoC: codecs: wcd: add common helper for wcd
codecs") patch.
 This will result in not parsing the device tree data and results in
zero mic bias values.

Fix this by calling wcd_dt_parse_micbias_info instead of
wcd_dt_parse_mbhc_data.

Applied to

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-7.0

Thanks!

[1/1] ASoC: codecs: wcd934x: fix typo in dt parsing
      https://git.kernel.org/broonie/sound/c/cfb385a8dc88

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
