Please port the code to raspbian

[parkour86]

I'm currently running Ubuntu 18.04 Kernel 4.15. The make command is failing to compile with a bunch of errors. I want to run this on a raspberry pi running raspbian kernel 4.14. Any way you could port the code to work on raspbian?

I tried an updated fork but that one seems to get errors too. https://github.com/mlnkrlc/uptime_hack

This one might work: https://github.com/Mic92/uptime_hack Currently tested on 5.1 kernel. Older versions are available in the history.

Nice work @Mic92, thanks for keeping this ancient toy module up to date! 👍
