Fix warning: This is kind of important

Browse Source 
Again another fix from https://github.com/prusa3d/Prusa-Firmware/pull/138 made by @Thess for the MK2 branch which i think is quite important.

Ardunio IDE 1.8.5 result with Compiler warnings set to "More" or "All"
```

I don't know if that helps making small pull requests as they are easier to review or it would make sense to combine few more.

Prusa should really review this pull [request](https://github.com/prusa3d/Prusa-Firmware/pull/138) again for the MK3 branch, as it was one that made warnings disapear in the MK2 branch and made finding new flaws in the code much much easier.
