My intention was to keep Cardbus support working with old defconfig files,

the PCI maintainers have a better idea.
Arnd,
I did a bit more investigation. My original .config had CONFIG_PCI_HOTPLUG not
defined, but did have CONFIG_CARDBUS and the various yenta modules turned on.
With your changes, the CONFIG_PCI_HOTPLUG overrode CARDBUS.
I thought mine was a corner case, but now I am not sure. As stated above, the
Debian 12 factory configuration for ppc32 does not turn on PCI hotplug, but the
x86_64 configuration for openSUSE Tumbleweed does. The x86_64 configuration in
Fedora 37 does not contain CONFIG_PCI_HOTPLUG, but does have CARDBUS set.
It seems that several distros may get the wrong result with this change,
