The patch
ASoC: Use card field to indicate whether a component is bound
has been applied to the asoc tree at
git://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

From: Lars-Peter Clausen lars@metafoo.de Date: Wed, 8 Jul 2015 20:47:44 +0200 Subject: [PATCH] ASoC: Use card field to indicate whether a component is bound
Use the card field of a component to indicate whether it is bound or not. This makes a certain sense given that the field contains the card the component is bound to and a component can only be bound to one card at a time. And it also requires to unset the card field when the component is unbound from the card.
This makes the probded flag redundant and it can be removed.
