[PATCH] ASoC: rt715: Remove unused hda_to_sdw

[PATCH] ASoC: rt715: Remove unused hda_to_sdw

[linux]

From: "Dr. David Alan Gilbert" <linux@treblig.org>

hda_to_sdw() has been unused since it was added in 2020 as part of the
commit d1ede0641b05 ("ASoC: rt715: add RT715 codec driver")

Remove it.

Thanks!

[1/1] ASoC: rt715: Remove unused hda_to_sdw
      commit: 37c42bde28f580ac5de4de838afd5eea72e40262

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
