qla2xxx first calls request_irq() and then does the setup of the queue entry data needed in the interrupt handlers in when using MSI-X. This could lead to a NULL pointer dereference when an IRQ fires between the request_irq() call and the assignment of the qentry data structure to the rsp->msix field. A possible case for such a race would be in the kdump case when the HBA's IRQs are still enabled but the driver is undergoing a new initialisation and thus is not aware of already activated IRQs in the HBA.
