The patch

ASoC: topology: Bind vendor specific kcontrol handlers before standard ones

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.

Vendor specific handlers should override standard handlers. So we can handle things in the order from specific to generic.

Add the pointer of struct soc_tplg as one argument, so no need to pass standard/vendor specific kcontrol handlers and their count.

From: Mengdong Lin mengdong.lin@intel.com Date: Tue, 18 Aug 2015 18:12:20 +0800 Subject: [PATCH] ASoC: topology: Add support for TLV bytes controls

Allow vendor drivers to define bespoke bytes ext handlers and IDs for TLV bytes controls. And the topology core will bind these handlers by matching IDs defined by the vendor driver and user space topology data file.

And TLV callback binding is moved to soc_tplg_kcontrol_bind_io(). This function process all handler binding now.
