Reset (aka power off) happens when the reset gpio is made active.
Change function name to ak4458_reset to match devicetree property "reset-gpios"

[1/1] ASoC: ak4458: correct reset polarity
      commit: e953daeb68b1abd8a7d44902786349fdeef5c297

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
