has been applied to the asoc tree at

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.

ADG is registering fixed rate clock for audio_clkout, but it had not been unregister clock when removing.

Salvator-X board is using ak4613 driver now, and it supports hw_constraints from commit 907cd8809eebc ("ASoC: ak4613: add hw_constraint rule for Sampling Rate"). And this calculation is using input clk. This ak4613 input clock is ADG clkout on Salvator-X.

Because ADG had not been unregister clkout when unbinding, it receives fixed rate clk register error when re-binding. Thus, ak4613 can't get correct input clock, and hw_constraints will be failed after re-binding. This means Salvator-X board can't use sound after unbind/bind.

This patch solves this issue.
