[PATCH -v3 13/47] PCI: Clean up rescan_bus_bridge_resize()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

Should only use it with bridge instead of bus.
It could get new subordinate. so can not use it with reguar bus.

In that case, user may need to make sure all children devices get removed
already before rescan.
