[PATCH 13/15] PCI/ACPI: Convert "pci_slot" sub-driver's functionalityto built-in only

From: Myron Stowe
Date: Fri Dec 07 2012 - 01:26:03 EST


The "ACPI PCI Slot Detection ("pci_slot")" sub-driver may be compiled as a
module. Kernel modules are instantiated somewhat randomly - the order in
which they are linked as the kernel as built - thus if there are any
dependencies on the ordering of attaching sub-drivers, they can not be
effectively dealt with.

This patch series resolves any potential sequencing inter-dependencies by
converting "pci_slot" sub-driver's functionality to being only supported
as statically built-in to the kernel. Inter-dependencies can then be
effectively handled by explicitly sequencing the addition of such
functionality.
