I have no idea how this is possible.

bcm43xx_main.c:

#ifdef CONFIG_BCM43XX_MAC80211_PCI
	err = ssb_pcihost_register(&bcm43xx_pci_driver);
	if (err)
		goto err_dfs_exit;
#endif


bcm43xx Kconfig:

config BCM43XX_MAC80211_PCI
	bool "BCM43xx PCI device support"
	depends on BCM43XX_MAC80211 && PCI
	select SSB_PCIHOST
	select SSB_DRIVER_PCICORE


ssb Kconfig:

config SSB_PCIHOST
	bool "Support for SSB on PCI-bus host"
	depends on SSB && PCI


ssb function declaration:

#ifdef CONFIG_SSB_PCIHOST
/* PCI-host wrapper driver */
extern int ssb_pcihost_register(struct pci_driver *driver);
static inline void ssb_pcihost_unregister(struct pci_driver *driver)
{
	pci_unregister_driver(driver);
}
#endif /* CONFIG_SSB_PCIHOST */


So what is going on? CONFIG_BCM43XX_MAC80211_PCI must be enabled.
Otherwise the func call would be ifdef'ed out. So but if
it is enabled, it would SELECT SSB_PCIHOST. Which would enable
the declaration and definition of ssb_pcihost_register().
What am I missing?
