Can’t figure out how to apply Kernel Oops fix

Sorry for the noob question, I am new to Linux. I have no idea how to apply a fix for a wi-fi issue I am having. I received this:

I tried to paste the topmost line in Terminal but it says ‘diff: unrecognized option ‘–git”.

How can I apply this fix? My machine runs Ubuntu 16.04.4 LTS

Thank you in advance!

“Kernal oops” with everything to do with bluetooth

Disclaimer, bluetooth may not be the problem, however the message box pops up after every pactl load-module module-bluetooth-discover command.

the dump file is below:
