[PATCH] ASoC: audio-graph: respawn Platform Support

[PATCH] ASoC: audio-graph: respawn Platform Support

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

commit 63f2f9cceb09f8 ("ASoC: audio-graph: remove Platform support")
removed Platform support from audio-graph, because it doesn't have
"plat" support on DT (simple-card has).
But, Platform support is needed if user is using
snd_dmaengine_pcm_register() which adds generic DMA as Platform.
And this Platform dev is using CPU dev.

Without this patch, at least STM32MP15 audio sound card is no more
functional (v5.13 or later). This patch respawn Platform Support on
audio-graph again.

[1/1] ASoC: audio-graph: respawn Platform Support
      commit: 5f939f49771002f347039edf984aca42f30fc31a

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
