Update codestyle

The following discussion from !1 (merged) should be addressed:

@xzima1 started a discussion: (+2 comments)
This mixes two comment styles (even Linus raged over these ;c)).
```
/*
 * comment
 */
```
vs.
```
/* hey, this is
 * a multi-line comment */
```
Personally, I treat the former as a sort of "block comment", while the latter as an "in-line comment". So here I would use the latter one.
