    ACPI / platform / LPSS: Enable async suspend/resume of LPSS devices · 8ce62f85
    Rafael J. Wysocki authored
    To seed up suspend and resume of devices included into Intel SoCs
    handled by the ACPI LPSS driver during system suspend, make
    acpi_lpss_create_device() call device_enable_async_suspend() for
    every device created by it.
    
    This requires acpi_create_platform_device() to be modified to return
    a pointer to struct platform_device instead of an int.  As a result,
    acpi_create_platform_device() cannot be pointed to by the .attach
    pointer in platform_handler directly any more, so a simple wrapper
    around it is necessary for this purpose.  That, in turn, allows the
    second unused argument of acpi_create_platform_device() to be
    dropped, which is an improvement.
