Applied "ASoC: rsnd: call free_irq() both DMA/PIO mode" to the asoc tree

[Mark Brown <broonie@kernel.org>]

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.

Please add any relevant lists and maintainers to the CCs when replying

Subject: [PATCH] ASoC: rsnd: call free_irq() both DMA/PIO mode

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.

Fixes: 701172dca15b ("ASoC: rsnd: don't use devm_request_irq() for SSI")
