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.

At first, soc_pcm_open() operation order is 1) CPU DAI startup 2) Component open 3) Codec DAI startup 4) rtd startup But here, 2) will call try_module_get() if component has module_get_upon_open flags. This means 1) CPU DAI startup will be operated *before* its module was loaded. DAI should be called *after* Component. Second, soc_pcm_close() operation order is 1) CPU DAI shutdown 2) Codec DAI shutdown 3) rtd shutdown 4) Component close soc_pcm_open() and soc_pcm_close() are paired function, but, its operation order is unbalance. This patch tidyup soc_pcm_open() order to Component -> rtd -> DAI.
