From d26fc87aa26953f97e6c93d07ee9cc1415e44e20 Mon Sep 17 00:00:00 2001 From: Markus Theil Date: Tue, 5 Sep 2017 14:04:03 +0200 Subject: [PATCH] igb_uio: fix MSI-X IRQ assignment with new IRQ function The patch which introduced the usage of pci_alloc_irq_vectors came after the patch which switched to non-threaded ISR (f0d1896fa1), but did not use non-threaded ISR, if pci_alloc_irq_vectors is used.
