Re: [PATCH v2 1/4] staging: pi433: Style fix - Correct long lines

[Marcus Wolf]

Hi everybody,

from my point of view, we should stay with the old implementation.

Ok - line is too long according to style guide. But these long lines are 
IMHO easy to read:
All four are pretty similar. By having all Tokens in exact the same length 
and having one below other, you can easily detect the differences between
the lines and that's important. As soon as you start to wrap them 
- regardless how - you won't be able to detect the differences that easy 
any more - and from my Point of view that's a disadvantage.

Cheers,

Marcus
