[alsa-devel] [PATCH v2] ASoC: soc-core: defer card probe until all component is added to list
From: Ajit Pandey ajitp@codeaurora.org
DAI component probe is not called if it is not present in component list during sound card registration. Check if component is available in component list for platform and cpu dai before soundcard registration.
Signed-off-by: Ajit Pandey ajitp@codeaurora.org Signed-off-by: Rohit kumar rohitkr@codeaurora.org --- Changes since v1: Moved component find logic to soc-core instead of machine driver as suggested by Mark.

The patch
ASoC: soc-core: defer card probe until all component is added to list
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

Right, we should have client_mutex lock before calling soc_find_component().
We will post fix.

While debugging Skylake audio stuff, I came across a kernel oops introduced by this commit.
It's quite late here and my brain is fried, submitting as is but my money is on the use of link->platform->of_node which is quite unlikely to work on ACPI platforms.
and btw you may want to fix the typos, it's registration, not registartion.

Right, either name or of_node should not be NULL for soc_find_component.
We will provide fix.
