From 3eefa790c9681a2dcbc923542dcd85b6989e8855 Mon Sep 17 00:00:00 2001 From: Jisheng Zhang Date: Thu, 20 Apr 2017 18:27:18 +0800 Subject: [PATCH] PCI: host: Mark PCIe/PCI (MSI) cascade ISR as IRQF_NO_THREAD Similar as commit 8ff0ef996ca0 ("PCI: host: Mark PCIe/PCI (MSI) IRQ cascade handlers as IRQF_NO_THREAD"), we should mark PCIe/PCI (MSI) IRQ cascade handlers in designware, qcom, and vmd as IRQF_NO_THREAD explicitly.
