[alsa-devel] Applied "ASoC: snd_soc_component_driver has snd_compr_ops" to the asoc tree

23 Oct 2017

The patch
ASoC: snd_soc_component_driver has snd_compr_ops
has been applied to the asoc tree at
git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git
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

Subject: [PATCH] ASoC: snd_soc_component_driver has snd_compr_ops
Platform will be replaced into Component in the future.
snd_soc_platform_driver has snd_compr_ops, but snd_soc_component_driver
doesn't have. To prepare for replacing, this patch adds snd_compr_ops on
component driver.
platform will be replaced into component, and its code will be removed.
But during replacing, both platform and component process code exists.
To keep compatibility, to avoid platform NULL access and to avoid
platform/component duplicate operation during replacing process, this
patch has such code. Some of this code will be removed when platform was
removed.
