6937 | * to enable the MSI-X vectors. Note that pci_enable_msix(), once invoked, | |
6938 | * enables either all or nothing, depending on the current availability of | |
6939 | * PCI vector resources. The device driver is responsible for calling the | |
6940 | * individual request_irq() to register each MSI-X vector with a interrupt | |
6941 | * handler, which is done in this function. Note that later when device is | |
6942 | * unloading, the driver should always call free_irq() on all MSI-X vectors | |
6943 | * it has done request_irq() on before calling pci_disable_msix(). Failure | |
