The patch

   ASoC: soc-core: merge card resources cleanup method

has been applied to the asoc tree at

   https://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: soc-core: merge card resources cleanup method

We need to cleanup card resources when snd_soc_instantiate_card() was
failed, or when snd_soc_unbind_card() was called.
But they are cleanuping card resources on each way.
Same code in many places makes code un-understandable.

This patch reuses soc_cleanup_card_resources() for cleanuping code
resource. Then, it makes avoiding cleanup order.
It will be called from snd_soc_instantiate_card() and
snd_soc_unbind_card().

Then, original soc_cleanup_card_resources() included
snd_soc_flush_all_delayed_work(), but it is now separated.
