Code does unconditional select for IOSF_MBI. IOSF_MBI driver depends on
CONFIG_PCI set but this is not specified anywhere.

Fixes: 5d32a66541c46 ("PCI/ACPI: Allow ACPI to be built without CONFIG_PCI set")

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)
