Wysocki" , Len Brown , Bjorn Helgaas Cc: Hans de Goede , linux-acpi@vger.kernel.org, linux-pci@vger.kernel.org Subject: [PATCH] ACPI/PCI: pci_link: use extended_irq union member when setting ext-irq shareable Date: Fri, 10 Apr 2020 15:14:42 +0200 Message-Id: <20200410131442.22842-1-hdegoede@redhat.com> MIME-Version: 1.0 X-Scanned-By: MIMEDefang 2.84 on 10.5.11.22 Sender: linux-pci-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-pci@vger.kernel.org The case ACPI_RESOURCE_TYPE_EXTENDED_IRQ inside acpi_pci_link_set() is correctly using resource->res.data.extended_irq.foo for most settings, but for the sharable setting it sofar has accidentally been using resource->res.data.irq.shareable instead of resource->res.data.extended_irq.shareable. Note that the old code happens to also work because the sharable field offset is the same for both the acpi_resource_irq and acpi_resource_extended_irq structs.
