Please stop and read all of the instructions provide, and then go read
the "how to submit your first patch" tutorial at kernelnewbies.org and
compare that to what you have been sending here.

You also keep sending stuff to quickly, patches should be, at the most,
sent once a day, and even then, that would be very quick.

Relax, take the weekend off, and come back next week with a proper
change based on the documentation.

thanks,
