From ae72f3156729541581f526b85883ca53a20df2fa Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Mon, 6 Dec 2021 23:27:42 +0100 Subject: PCI/MSI: Make arch_restore_msi_irqs() less horrible. Make arch_restore_msi_irqs() return a boolean which indicates whether the core code should restore the MSI message or not. Get rid of the indirection in x86.
