PCI: pciehp: Ignore interrupts during D3coldpci/pm
If a hotplug port is suspended to D3cold, its slot status register cannot be read. If that hotplug port happens to share its IRQ with other devices, whenever an interrupt occurs for one of these devices, pciehp logs a "no response from device" message and tries to read the PCI_EXP_SLTSTA register, even though we know that will fail. Ignore interrupts while we're in D3cold. [bhelgaas: changelog] Signed-off-by: Lukas Wunner <lukas@wunner.de> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
