[alsa-devel] Applied "ASoC: soc-core: add snd_soc_del_component_unlocked()" to the asoc tree

[Mark Brown]

The patch

   ASoC: soc-core: add snd_soc_del_component_unlocked()

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.5

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: soc-core: add snd_soc_del_component_unlocked()

It is easy to read code if it is cleanly using paired function/naming,
like start <-> stop, register <-> unregister, etc, etc.
But, current ALSA SoC code is very random, unbalance, not paired, etc.
It is easy to create bug at the such code, and is difficult to debug.

Now ALSA SoC has snd_soc_add_component(), but there is no paired
snd_soc_del_component(). Thus, snd_soc_unregister_component() is
calling cleanup function randomly. it is difficult to read.
This patch adds missing snd_soc_del_component_unlocked() and
balance up code.
