I don't care.

Keeping in line may make sense in case of coding style, but its
no replacement for understanding the code you're copying around.
The same check in prio_get is correct and necessary, while in
the function you add it is incorrect and covers up potential bugs.

So please remove it so we can stop this pointless discussion.
