Merge #6687
6687: Fix assignment in condition. r=colby-swandale a=voxik
I am not sure what is the purpose of this code neither I have idea if the proposed fix is actually correct, but I am quite sure that the condition does not make sense, because the assignment takes priority and therefore the branch is never accessible. So I just take a guess and submitted this PR to open the discussion ;)
Please note this was pointed out by Coverity scan of the Bundler code:
