From 91f7d2dbf952f54442fa81bb62f78ee023179bf9 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 15 Dec 2021 15:01:59 +0100 Subject: [PATCH] x86/xen: Use correct #ifdef guard for xen_initdom_restore_msi() The #ifdef check around the definition doesn't match the one around the declaration, leading to a link failure when CONFIG_XEN_DOM0 is enabled but CONFIG_XEN_PV_DOM0 is not: x86_64-linux-ld: arch/x86/kernel/apic/msi.o: in function `arch_restore_msi_irqs': msi.c:(.text+0x29a): undefined reference to `xen_initdom_restore_msi' Change the declaration to use the same check that was already present around the function definition. Fixes: ae72f3156729 ("PCI/MSI: Make arch_restore_msi_irqs() less horrible.")
