With this, quite some GIT rebasing work needs to be done, and adding this one liner at a later time (thus rebasing it) is way easier. To be sure this will not be forgotten afterwards, I've already posted a patch applying the exact change at [1]. Thank you very much! [1] https://patchwork.linuxtv.org/patch/42393/
Thank you! -- Gustavo A. R. Silva
