Prev: [PATCH 13/18] staging: cx25821: call disable_pci_device() if pci_probe() failed
Next: [GIT] dmaengine/async_tx update for 2.6.36

Driver should call disable_pci_device() if it returns from pci_probe()
with error. Also it must not be called if pci_request_region() fails as
it means that somebody uses device resources and rules the device.
