deepin pr auto review

关键摘要:

• 在ddbusinterface.cpp文件中，使用baSignal.data()替换baSignalName.data()可能会导致潜在的内存泄漏，因为baSignal在后续代码中被修改，而baSignalName没有被重新创建。
• method.parameterCount()的调用应该在method.invoke()之前检查，以确保方法有足够的参数。
• qDebug()函数中的格式字符串应该使用%s来格式化字符串，而不是%d，因为propName是一个字符串。
• auto关键字在C++11中引入，应该确保编译器支持C++11或更高版本。
