[PATCH 07/18] isdn: avm: call disable_pci_device() if pci_probe() failed

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

 



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