Commit Message

  We have SOF and generic ACP support enabled for Rembrandt and
pheonix platforms on some machines. Since we have same PCI id
used for probing, add check for machine configuration flag to
avoid conflict with newer pci drivers. Such machine flag has
been initialized via dmi match on few Chrome machines. If no
flag is specified probe and register older platform device.

You should mention here that the PCI ID is the same but the revision
is different to make this clearer for the commit message.

Whitespace looks not aligned here.  I think it's a mix of tabs and 
spaces in this section.

This 'flag' variable seems unnecessary if it's just used in one place 
and never evaluated.

Applied to

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-next

Thanks!

[1/1] ASoC: amd: Add check for acp config flags
      commit: bddcfb0802eb69b0f51293eab5db33d344c0262f

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
