[alsa-devel] Applied "ASoC: Intel: use common helpers to detect CPUs" to the asoc tree

The patch
ASoC: Intel: use common helpers to detect CPUs
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.3
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: use common helpers to detect CPUs
We have duplicated code in multiple locations (atom, machine drivers,
SOF) to detect Baytrail, Cherrytrail and other SOCs. This is not very
elegant, and introduces dependencies on CONFIG_X86 that prevent
COMPILE_TEST from working.
Add common helpers to provide same functionality in a cleaner
way. This will also help support the DMI-based quirks being introduced
to handle SOF/SST autodetection.
