i82875p_edac: fix overflow device resource setup
When I do "modprobe i82875p_edac" on my Asus P4C800 MB on kernels 2.6.26 or later, the module load fails due to BAR 0 collision. On 2.6.25 the module loads just fine. The overflow device on the MB seems to be hidden and its resources are not allocated at normal PCI bus init. Log shows the missing resource problem: EDAC DEBUG: i82875p_probe1() PCI: 0000:00:06.0 reg 10 32bit mmio: [fecf0000, fecf0fff] pci 0000:00:06.0: device not available because of BAR 0 [0xfecf0000-0xfecf0fff] collisions EDAC i82875p: i82875p_setup_overfl_dev(): Failed to enable overflow device The patch below fixes this by calling pci_bus_assign_resources() after the overflow device is revealed and added to the bus. With this patch I am again able to load and use the module.
