    wmi: convert acpi_get_handle() to acpi_has_method() · 54f14c27
    Zhang Rui authored
    acpi_has_method() is a new ACPI API introduced to check
    the existence of an ACPI control method.
    It can be used to replace acpi_get_handle() in the case that
    1. the calling function doesn't need the ACPI handle of the control method.
    2. the calling function doesn't care the reason why the method is unavailable.
    Convert acpi_get_handle() to acpi_has_method()
    in drivers/platform/x86/wmi.c in this patch.
