The patch
ASoC: soc-pcm: add soc_pcm_components_open()
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.3
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.

soc-pcm.c has soc_pcm_components_close() but not have its open() side function. This kind of unbalance function is very unreadable.
And, current error handling is not correct. Because it is using for_each_rtdcom() loop, we need to call soc_pcm_components_close() anyway even though CPU DAI .startup() failed.
This patch adds soc_pcm_components_open(), and fixup error handling issue.
