Ok, I can do that. In the commit message I described just one issue
because it is only one patch, I didn't want it to look like I was
changing different issues in just one patch.

Yes, I'm sending this email to Matthew too, because I don't know
exactly how to proceed as Hans asked me to made some corrections too. 
I've made these changes because checkpatch has indicated and with this
line break, checkpatch does not indicate any check or warning anymore.
But I can undo that too, I just don't know what I'm supposed to do with
so many opposite opinions.
