When BCM47XX_SSB is enabled and SSB_PCIHOST is disabled, it results in the
following Kbuild warning:
WARNING: unmet direct dependencies detected for SSB_B43_PCI_BRIDGE
Depends on [n]: SSB [=y] && SSB_PCIHOST [=n]
Selected by [y]:
- BCM47XX_SSB [=y] && BCM47XX [=y] && PCI [=y]
The reason is that BCM47XX_SSB selects SSB_B43_PCI_BRIDGE without
depending on or selecting SSB_PCIHOST while SSB_B43_PCI_BRIDGE depends on
SSB_PCIHOST. This can also fail building the kernel as demonstrated in a
bug report.
Honor the kconfig dependency to remove unmet direct dependency warnings
and avoid any potential build failures.
