From cf48a9052e82b8fff57c2f2e2d53dee6496ee133 Mon Sep 17 00:00:00 2001 From: Heyi Guo Date: Tue, 4 Feb 2020 09:43:20 +0800 Subject: [PATCH] arm/virt/acpi: remove meaningless sub device "RP0" from PCI0 The sub device "RP0" under PCI0 in ACPI/DSDT does not contain any method or property other than "_ADR", so it is safe to remove it.
