This patch-set fixes the following issues in the vmbus driver (vmbus_drv.c): Make vmbus driver a platform pci device and cleanup root device management and irq allocation (patches 1/12 through 3/12): 1) Make vmbus driver a platform pci driver. 2) Cleanup root device management. 3) Leverage the pci model for allocating irq. General cleanup of vmbus driver (patches 4/12 though 12/12): 1)
