Applied "ASoC: Intel: Skylake: Reset stream to link mapping" to the spi tree

[Mark Brown <broonie@xxxxxxxxxx>]

The patch

   ASoC: Intel: Skylake: Reset stream to link mapping

has been applied to the spi tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.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

Subject: [PATCH] ASoC: Intel: Skylake: Reset stream to link mapping

By default all the streams are mapped to all links after controller is
reset which causes stream to be broadcast on all the links.

This patch resets the stream-link mapping after controller reset. The
stream is mapped later to the appropriate link as part of stream setup.
