Im not sure if this is the right commit as i dont know what way it
works but basically the very first commit caused the issue of me not
being able to use git and when i typed the git bisect bad it said
this:
ownerx35 at ownerx35-VirtualBox:~/Desktop/linux$ git bisect bad
Bisecting: 21 revisions left to test after this (roughly 5 steps)
[774a93aa647f8939867c8ff956847bc63dd51cb3] usbhid: prevent deadlock
