License of input-event-codes.h

Hello All

I want to use input-event-codes.h for my project.
https://cgit.freebsd.org/src/tree/sys/dev/evdev/input-event-codes.h

However, I found a file with same name that differs only copyright and
license notation in Linux kernel.
https://github.com/torvalds/linux/blob/master/include/uapi/linux/input-event-codes.h

How should I interpret the difference between the two licenses when
using it for my project?
Also, which one is the original?

Best Regards
