It is much more efficient to use acpi_find_child_device() for child devices lookup in acpi_pci_find_device() and pass ACPI_COMPANION(dev->parent) to it directly instead of obtaining ACPI_HANDLE() of ACPI_COMPANION(dev->parent) and passing it to acpi_find_child() which has to run acpi_bus_get_device() to obtain ACPI_COMPANION(dev->parent) from that again.
