Commit Message

Kuninori Morimoto Aug. 6, 2024, midnight UTC 
Bespoke trigger support was added when Linux v3.5 by this patch.

	commit 07bf84aaf736781a283b1bd36eaa911453b14574
	("ASoC: dpcm: Add bespoke trigger()")

test-component driver is using it, but this is because it indicates used
function for debug/trace purpose. Except test-component driver, bespoke
trigger has never been used over 10 years in upstream.

We can re-support it if needed in the future, but let's remove it for now,
because it just noise in upstream.

[1/1] ASoC: remove bespoke trigger support
      commit: 7d2fb3812acde0a76e0d361877e8295db065f9f4

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
