OK, thanks. I assume that's a Kconfig mistake in the wireless tree.

But it looks like a real minefield:


+static inline void b44_pci_exit(void)
+{
+#ifdef CONFIG_B44_PCI
+ ssb_pcihost_unregister(&b44_pci_driver);
+#endif
+}
and

+#ifdef CONFIG_BCM43XX_MAC80211_PCI
+ ssb_pcihost_unregister(&bcm43xx_pci_driver);
+#endif

and

+#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 */

That looks waaaaaay more complicated than it needs to be.
I'm thinking that the first two ifdefs should be removed and that third one
needs a #else clause which implements stubs and that b44 Kconfig needs to
be taught about CONFIG_SSB_PCIHOST in some fashion.

Or something like that.
