ASoC: simple-scu-card: use cpu/codec pointer on graph_dai_props

has been applied to the asoc tree at

https://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.

From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com Date: Tue, 11 Dec 2018 03:25:27 +0000 Subject: [PATCH] ASoC: simple-scu-card: use cpu/codec pointer on graph_dai_props

In DPCM case, it uses CPU-dummy / dummy-Codec dai links, and non DPCM case, it uses CPU-Codec dai links.

Now, we want to merge simple-card and simple-scu-card.

These sound cards are using silimar but not same logic on each functions. Then, of course we want to share same logic. To compromise, this patch uses cpu/codec pointer on simple-scu-card. It is same logic with simple-card, thus easy merging. This is prepare for merging simple card
