From 0111d600f0f456d09eb0ff6ac217fa5f30ae79ab Mon Sep 17 00:00:00 2001 From: Jeremy Linton Date: Sun, 8 Mar 2026 23:59:30 -0500 Subject: [PATCH] PCI: of: Reduce severity of missing of_root error message Arm64 kernels are frequently built dual ACPI/DT, and then boot in ACPI mode. In this case, there won't be an of_root, except for rare DT described PCIe boards. As a result, users in the common case see this high priority worrying message, despite the machine working as expected. Reduce this message to pr_debug() to avoid unnecessary noise.
