Bjørn Mork ec53250320 [media] siano: fix divide error on 0 counters ... GIT_AUTHOR_DATE=1376465691 I took a quick look at the code and wonder if the problem is caused by an initial zero statistics message? This is all just a wild guess, but if it is correct, then the attached untested patch might fix it...
