From: Rafael J. Wysocki <rjw@xxxxxxx> Make acpi_pci_osc_control_set() attempt to find the handle of the _OSC object under the given PCI root bridge object after verifying that its second argument is correct and that there is a struct acpi_pci_root object for the given root bridge handle. This is more logical than the old code and it matches the code ordering in acpi_pci_osc_control_query(). Signed-off-by: Rafael J.
