[PATCH 1/3] PCI: don't say we claimed a resource if we failed

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

 



pci_claim_resource() can fail, so pay attention and only claim success
when it actually succeeded.  If pci_claim_resource() fails, it prints a
useful diagnostic.
