[rk3588 debain]cpu死锁问题解决

1 问题

        rk3588机器上运行客户如下程序程序发生“BUG: spinlock recursion on CPU#0”

./rtsp RtspWrapper.xml

        应用程序功能是：ip摄像头推流，通过rtsp协议拉流，对视频流做裁剪，缩放工作。首先，根据视频帧率每秒钟处理25张图片。其次，每张图片都会做颜色转换和缩放。最后，会根据图像里人的个数并行执行:颜色转换，裁剪，缩放。总体流程:取流，vpu解码，gpu图像处理，npu算法分析

        发生的bug日志如下所示

2 解决问题

        原来系统的rknpu版本为0.82，版本太低了，更新 rknpu的版本为 0.96 解决该问题，更新的代码文件如下所示。
