Because acpi_walk_dep_device_list() is only called by the code in the
file in which it is defined, make it static, drop the export of it
and drop its header from acpi.h.

Actually, acpi_walk_dep_device_list() was split out as a
helper function used to implement acpi_dev_clear_dependencies()
because it will be used outside of drivers/acpi.

Not exactly.

Specifically it will be used in the new intel_skl_int3472 driver:
https://patchwork.kernel.org/project/platform-driver-x86/patch/20210603224007.120560-6-djrscally@gmail.com/

That driver will use acpi_dev_get_first_consumer_dev() which is based
on acpi_walk_dep_device_list(), but still defined in
drivers/acpi/scan.c.

Which I plan to merge into pdx86/for-next today, I've just merged
your linux-pm/acpi-scan PULL-req which exports acpi_walk_dep_device_list()
as preparation for this.

No, the acpi_walk_dep_device_list() is a leftover there AFAICS.

If it needs to be exported in the future, that still can be done.  ATM
the export isn't necessary.

Thanks!
