[PATCH 1/2] ASoC: fsl_aud2htx: register platform component before registering cpu dai
There is no defer probe when adding platform component to snd_soc_pcm_runtime(rtd), the code is in snd_soc_add_pcm_runtime()
snd_soc_register_card() -> snd_soc_bind_card() -> snd_soc_add_pcm_runtime() -> adding cpu dai -> adding codec dai -> adding platform component.
So if the platform component is not ready at that time, then the sound card still registered successfully, but platform component is empty, the sound card can't be used.
As there is defer probe checking for cpu dai component, then register platform component before cpu dai to avoid such issue.
And the behavior of imx_pcm_dma_init() is same as common devm_snd_dmaengine_pcm_register(), so use devm_snd_dmaengine_pcm_register() instead

Call pm_runtime_disable() when error happens in probe()

Thanks!
[1/2] ASoC: fsl_aud2htx: register platform component before registering cpu dai commit: ea532c29972df96fda20393d9bf057e898f5e965 [2/2] ASoC: fsl_aud2htx: Add error handler for pm_runtime_enable commit: b1cd3fd42db7593a2d24c06f1c53b8c886592080
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
