[PATCH 5/8] ACPI, PCI: PCI MSI _OSC support capabilities called when root bridge added

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

 



ACPI, PCI: PCI MSI _OSC support capabilities called when root bridge added

The _OSC capabilityy OSC_MSI_SUPPORT is set when the root
bridge is added with pci_acpi_osc_support(), so we no longer
need to do it in the PCI MSI driver.
