[PATCH] s390/pci: PCI_IOV_RESOURCES loop refactoring in zpci_map_resources

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

 



This patch alters the for loop iteration scheme in zpci_map_resources
to make it more usual. Thus, the patch generalizes the style for
PCI_IOV_RESOURCES iteration and improves readability.
