Max msuraev at sysmocom.deHi.
I appreciate your intention on making code better but do you really
think that re-posting those emails worth your time? I think all the devs
who could fix it are receiving it directly from Coverity already, and
for others it just creates additional noise in ML.
I also do not think that there's any urgency with those - we have about
500 of unfixed defects detected by Coverity so far, +-2 do not make big
difference compared to that amount.
