From: Jeremy Linton Date: Mon, 9 Mar 2026 04:59:30 +0000 (-0500) Subject: PCI: of: Reduce severity of missing of_root error message X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=0111d600f0f456d09eb0ff6ac217fa5f30ae79ab;p=thirdparty%2Flinux.git 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.
