This patch is sended from address chinayanlei2002@163.com you need to 
send it from yan_lei@dahuatech.com this was probably mistake?

Also please write commit message. Always good to write how did you spot 
this and what message some analyzer showed to you. This way everyone 
else will can verify and maybe even learn to use new tools. This also 
looks like it really fix something so this needs fix tag so it can be 
easily back ported to stable.
