[PATCH v9 02/11] PCI: Add root bus children dev's res to fail list

From: Yinghai Lu
Date: Fri Jan 18 2013 - 02:55:55 EST


We can stop trying according to try_number now and do not need to use
root_bus checking as stop sign.

In extreme case we could need to reallocate resource for device just
under root bus. For pci root bus hot-add, we need to retry to assign
resources to pci devices just under pci root bus.
