Here is the executive summary:

I have a changeset that separates ACPI from PCI on 4.21. CONFIG_ACPI
used to select PCI. This is no longer true.

You can build an ACPI system without any PCI devices.

So there's no dependency and I can just apply this?

Anytime we change the Kconfig settings for audio, we get all kinds of 
problems with randconfig and 0day/kbuild due to depend/select issues. 
I'd like to give this a spin first, can you share a link to the entire

IMO it would be better to say

"After commit 5d32a66541c46 (PCI/ACPI: Allow ACPI to be built without
CONFIG_PCI set) dependencies on CONFIG_PCI that previously were
satisfied implicitly through dependencies on CONFIG_ACPI have to be
specified directly.  For this reason, add a direct dependency on
CONFIG_PCI to the IOSF_MBI driver."

If you did that, the reviewers would know upfront what this was about
and that might save at least one back-and-forth e-mail exchange in
each case.

But, of course, the changelog doesn't even match the patch contents in
this particular case.  Please fix that.

Thanks, will do. I think this patchset will uncover additional 
inconsistencies, e.g. for legacy Haswell/Broadwell/Baytrail the machine 
drivers depend on X86_INTEL_LPSS, which depends in turn on PCI, but the 
platform drivers only depend on ACPI, so there is a risk of creating a 
config that makes no sense (or should only be used for COMPILE_TEST)

I'm assuming this goes in through the acpi tree, correct?
