[alsa-devel] Applied "ASoC: atmel: atmel_wm8904: consider CPU-Platform possibility unnecessary Platform"" to the asoc tree

[Mark Brown]

The patch

   ASoC: atmel: atmel_wm8904: consider CPU-Platform possibility unnecessary Platform"

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.3

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

Subject: [PATCH] ASoC: atmel: atmel_wm8904: consider CPU-Platform possibility
 unnecessary Platform"

commit 3609750e9d4ba9db ("ASoC: atmel: atmel_wm8904: don't select
unnecessary Platform")

Current ALSA SoC avoid to add duplicate component to rtd,
and this driver was selecting CPU component as Platform component.
Thus, above patch removed Platform settings from this driver,
because it assumed these are same component.

But, some CPU driver is using generic DMAEngine, in such case, both
CPU component and Platform component will have same of_node/name.
In other words, there are some components which are different but
have same of_node/name.

In such case, Card driver definitely need to select Platform even
though it is same as CPU.
It is depends on CPU driver, but is difficult to know it from Card driver.
This patch reverts above patch.
