Subject: [PATCH v1] scsi: be2iscsi: Fix MSI-X IRQ cleanup
Date: Sun, 2 Aug 2026 21:42:24 -0400 [thread overview]
Message-ID: <20260803014224.614347-1-dbgh9129@gmail.com> (raw)
beiscsi_init_irqs() uses j to walk previously registered MSI-X vectors
when unwinding an allocation or request_irq() failure, but passes i to
pci_irq_vector(). Consequently, each free_irq() targets the failing
vector instead of the vector associated with be_eq[j].
Use j to release the same vector that was registered. This ensures all
successfully requested IRQs are freed before initialization failure tears
down the HBA.
Fixes: 831488669a33 ("scsi: be2iscsi: switch to pci_alloc_irq_vectors")
