Subject: PCI: host: Mark PCIe/PCI (MSI) cascade ISR as IRQF_NO_THREAD
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3eefa790c9681a2dcbc923542dcd85b6989e8855;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

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.
