Avoid by checking the is_pciehp flag instead of is_hotplug_bridge when deciding whether to create a subdevice. The latter encompasses ACPI slots whereas the former doesn't. The superfluous subdevice has no real negative impact, it occupies memory and interrupt resources but otherwise just sits there waiting for interrupts from the slot that are never signaled.

[PATCH AUTOSEL 6.14 001/642] kconfig: merge_config: use an empty file as initfile

by Sasha Levin

From: Daniel Gomez <da.gomez(a)samsung.com> [ Upstream commit a26fe287eed112b4e21e854f173c8918a6a8596d ] The scripts/kconfig/merge_config.sh script requires an existing $INITFILE (or the $1 argument) as a base file for merging Kconfig fragments. However, an empty $INITFILE can serve as an initial starting point, later referenced by the KCONFIG_ALLCONFIG Makefile variable if -m is not used. This variable can point to any configuration file containing preset config symbols (the merged output) as stated in Documentation/kbuild/kconfig.rst. When -m is used $INITFILE will contain just the merge output requiring the user to run make (i.e. KCONFIG_ALLCONFIG=<$INITFILE> make <allnoconfig/alldefconfig> or make olddefconfig). Instead of failing when `$INITFILE` is missing, create an empty file and use it as the starting point for merges.
