This reverts commit 33683cbf49b5412061cb1e4c876063fdef86def4.

dai_link->platform is needed. The platform component is
"snd_dmaengine_pcm", which is registered from cpu driver,

If dai_link->platform is not assigned, then platform
component will not be probed, then there will be issue:

aplay: main:831: audio open error: Invalid argument

Please include human readable descriptions of things like commits and
issues being discussed in e-mail in your mails, this makes them much
easier for humans to read especially when they have no internet access.
I do frequently catch up on my mail on flights or while otherwise
travelling so this is even more pressing for me than just being about
making things a bit easier to read.

Please submit patches using subject lines reflecting the style for the
subsystem, this makes it easier for people to identify relevant patches.
Look at what existing commits in the area you're changing are doing and
make sure your subject lines visually resemble what they're doing.
There's no need to resubmit to fix this alone.

Thanks!

      commit: 09cda705860125ffee1b1359b1da79f8e0c77a40

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

And sorry to my noise patch. I understood the issue.

Can I ask 2 things ?

My original patch removed 3 platforms.
Then, I understood that 2 of them are used as
soc-generic-dmaengine-pcm (= 1st, 3rd platform).

I think we want to have comment here that
why dummy component is needed. Can you agree ?

I wonder how about 2nd platform ? Is it same ?
I'm asking because it doesn't have of_node which other 2 platforms have.

Thank you for your help !!

Best regards
