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.

SOF module load/unload tests show nasty recurring warnings:
WARNING: CPU: 5 PID: 1339 at sound/core/control.c:466 snd_ctl_remove+0xf0/0x100 [snd] RIP: 0010:snd_ctl_remove+0xf0/0x100 [snd]
This regression was introduced by the removal of the call to soc_remove_link_components() before soc_card_free() is invoked.
Go back to the initial order but only call soc_remove_link_components() once.
