From 3dfa64aecbafc288216b2790438d395add192c30 Mon Sep 17 00:00:00 2001 From: Lu Baolu Date: Mon, 12 Feb 2024 09:22:27 +0800 Subject: iommu: Make iommu_report_device_fault() return void As the iommu_report_device_fault() has been converted to auto-respond a page fault if it fails to enqueue it, there's no need to return a code in any case. Make it return void.
