The 'sound-name-prefix' is used to prepend suitable strings to a
component widgets or controls. This is helpful when there are
multiple instances of the same component. Add relevant json-schema
and is inspired from sound-name-prefix.txt documentation.

You can't remove the property. This is now a warning in linux-next:

Just 'sound-name-prefix: true' is fine

Here too, but I guess we don't have any example to throw a warning?

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
