[PATCH v2 6/9] nvme: Use pci_enable_msi_range() and pci_enable_msix_range()

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

 



As result deprecation of MSI-X/MSI enablement functions
pci_enable_msix() and pci_enable_msi_block() all drivers
using these two interfaces need to be updated to use the
new pci_enable_msi_range() and pci_enable_msix_range()
interfaces.
