From e8e2b88f5feb852904598cbe8746cc5b3c0022ab Mon Sep 17 00:00:00 2001 From: Nick Hainke Date: Wed, 28 Jul 2021 23:18:01 +0200 Subject: mediatek: mt7623: import patch to fix msi warning The 1st generation MediaTek PCIe host bridge cannot handle Message Signaled Interrupts (MSIs). The core PCI code is not aware that MSI is not available. This results in warnings of the form: WARNING: CPU: 2 PID: 112 at include/linux/msi.h:219 pci_msi_setup_msi_irqs.constprop.8+0x64/0x6c Modules linked in: ahci(+) libahci libata sd_mod scsi_mod gpio_button_hotplug CPU: 2 PID: 112 Comm: kmodloader Not tainted 5.10.52 #0 Hardware name: Mediatek Cortex-A7 (Device Tree) Import patches that introduce the 'no_msi' attribute to signal missing MSI support to the core PCI.
