I gave you the exact subject to use... I would list out the parts
rather than 'TAS58XX'. Your goal with the subject is it should be
unique enough that the exact same subject never appears again in the
commit history. With the wildcards, it may.

Thanks!

[1/2] ASoC: tas2781: Support more newly-released amplifiers tas58xx in the driver
      commit: 53a3c6e222836a23e8e0693395584aefc456dca6
[2/2] ASoC: dt-bindings: ti,tas2781: Add TAS58XX
      (no commit info)

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
