Subject: Re: [PATCH v5 07/20] platform/x86: pmc_atom: Move to intel
 sub-directory

This means that pmc_atom will now not be build if X86_PLATFORM_DRIVERS_INTEL
is not set (and PCI is enabled). Which will cause missing pmc_atom_read/_write
symbols in drivers/acpi/acpi_lpss.c. So I have dropped this patch from the
set, while applying the rest.

Note I'm thinking that we should just remove the whole X86_PLATFORM_DRIVERS_INTEL
Kconfig option and in the drivers/platform/x86/Makefile replace:

obj-$(CONFIG_X86_PLATFORM_DRIVERS_INTEL)                += intel/

with:

obj-y                                                   += intel/

This will also allows us to fix the scu issue without needing any
changes to drivers/mfd/Kconfig .

But this can all wait for the 2nd round of renames after 5.15-rc1.

For now I'm moving forward with this v5 series, except with this
patch dropped.

Regards,

Hans
