My personal taste is also to omit these breaks but I am pretty sure I
saw some tooling issuing a warning about falling through the switch-
case back when I wrote this. Most probably checkpatch didn't like that
back then. Anyways - if you have no warnings from any of the tools -
this indeed looks better (to me) without the break :)

Actually - my personal taste would be to also get rid of the empty
default here - but I guess it was also added to make some tool happy...
