[PATCH v2 5/9] PCI/AER: Unexport pci_aer_clear_nonfatal_status()

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

 



Since pci_aer_clear_nonfatal_status() is used only internally, move
its declaration to the PCI internal header file. Also, no one cares
about return value of pci_aer_clear_nonfatal_status(), so make it void.
