[PATCH] ASoC: tas2783A: remove unused tas25xx_(de)register_misc() functions

[Ethan Nelson-Moore]

The tas2783 driver defines two functions tas25xx_register_misc and
tas25xx_deregister_misc which have stub implementations. It uses
external implementations if CONFIG_SND_SOC_TAS2783_UTIL is enabled, but
that symbol has never been present in the kernel. Therefore, these
functions are entirely unused. Remove them.

Discovered while searching for CONFIG_* symbols referenced in code but
not defined in any Kconfig file.

      https://git.kernel.org/broonie/sound/c/fda53b646717

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
