That's great, but you need to send these all independently to each subsystem as needed. Having it all in one series doesn't work for any of the maintainers of any of the subsystems. And I'm glad to see this work happening, thanks for doing that! greg k-h

If that's the case don't send them in a series, it makes things more
complicated to apply and the CCs cause more mail. Split independent
things up by subsystem.

I initially had idea of creating a macro that made all of them depend on the macro but later dropped as I wanted to check if that is good or a bad idea. I just asked you in the thread 2/9. > And I'm glad to see this work happening, thanks for doing that! > Thanks for adding faux interface!

[6/9] ASoC: soc-utils: Transition to the faux device interface commit: 18abb3797f1ceca97a705aa1c14cbec5c6fcab79 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
Recently when debugging why one of the scmi platform device was not showing up under /sys/devices/platform/firmware:scmi instead was appearing directly under /sys/devices/platform, I noticed the new faux interface /sys/devices/faux. Looking through the discussion and the background, I got excited and took the opportunity to clear all the platform devices under /sys/devices/platform on the Arm Juno/FVP platforms that are really faux devices. Only the platform devices created for the device nodes from the DT remain under /sys/devices/platform after these changes. All the patches are independent of each other.
