When acpi_evaluate_object() is passed ACPI_ALLOCATE_BUFFER, the caller
must kfree the returned buffer if AE_OK is returned.
Call Trace:
wmab_execute
-> wmi_evaluate_method
-> acpi_evaluate_object
Thus if callers of wmab_execute() pass ACPI_ALLOCATE_BUFFER, the return
buffer must be kfreed if wmab_execute return AE_OK.
