From 62dd55fcf736994958eb5706cee5806480acfe25 Mon Sep 17 00:00:00 2001 From: Igor Mammedov Date: Thu, 2 Mar 2023 17:15:40 +0100 Subject: [PATCH] acpi: pci: move BSEL into build_append_pcihp_slots() Generic PCI enumeration code doesn't really need access to BSEL value, it is only used as means to decide if hotplug enumerator should be called. Use stateless object_property_find() to do that, and move the rest of BSEL handling into build_append_pcihp_slots() where it belongs. This cleans up generic code a bit from hotplug stuff and follow up patch will remove remaining call to build_append_pcihp_slots() from generic code, making it possible to use without ACPI PCI hotplug dependencies.
