The patch
ASoC: rsnd: call free_irq() both DMA/PIO mode
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.

commit 701172dca15b ("ASoC: rsnd: don't use devm_request_irq() for SSI") exchanged devm_request_irq() to request_irq() for SSI, because SSI will fallback into PIO mode if DMA doesn't work. But, because of it, PIO mode needed to call free_irq() when removing, not only DMA mode. This patch call free_irq() both PIO/DMA. Otherwise, rsnd IRQ handler will be increased if user tried many unbind/bind.
