[PATCH V2 4/6] scsi: set shost->use_managed_irq if driver uses managed irq

Fri Jul 2 08:05:53 PDT 2021
Set shost->use_managed_irq if irq vectors are allocated via
pci_alloc_irq_vectors_affinity(PCI_IRQ_AFFINITY) or
pci_alloc_irq_vectors(PCI_IRQ_AFFINITY).
The rule is that driver has to tell scsi core if managed irq is used.
