Lukas Wunner e8a6123e9e x86/platform/intel-mid: Retrofit pci_platform_pm_ops ->get_state hook ... Commit cc7cc02bad ("PCI: Query platform firmware for device power state") augmented struct pci_platform_pm_ops with a ->get_state hook and implemented it for acpi_pci_platform_pm, the only pci_platform_pm_ops existing till v4.7. However v4.8 introduced another pci_platform_pm_ops for Intel Mobile Internet Devices with commit 5823d0893e ("x86/platform/intel-mid: Add Power Management Unit driver"). It is missing the ->get_state hook, which is fatal since pci_set_platform_pm() enforces its presence. Andy Shevchenko reports that without the present commit, such a device "crashes without even a character printed out on serial console and reboots (since watchdog)". Retrofit mid_pci_platform_pm with the missing callback to fix the breakage.
