The patch
ASoC: Intel: Skylake: Fix to use correct macros for the path iteration
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
to this mail.
Thanks,
Mark

Subject: [PATCH] ASoC: Intel: Skylake: Fix to use correct macros for the path
iteration
In case of playback, for the BE dai source path should be iterated to find
the pipe params. With sink path iterated, this resulted in a loop and kernel
panic with page request failure.
Similar are the cases for Capture and FE dais. Using correct macros to fix
the panic
