ASoC: rockchip: i2s: Adjust devm usage

Remove use of snd_soc_unregister_component in remove function as devm_snd_soc_register_component in probe function automatically handles it.

Also, convert call of snd_dmaengine_pcm_register to managed resource function devm_snd_dmaengine_pcm_register and remove usage of snd_dmaengine_pcm_unregister in probe and remove functions.

The patch

ASoC: rockchip: i2s: Adjust devm usage

has been applied to the asoc tree at

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git

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
