Both the function and the struct it takes have the same name, which of
course is perfectly valid C. However, IMO it would be easier to grep for
the function/struct individually if they had different names.

I guess a newline is needed here to make this a valid kerneldoc comment
(the trailing '*' indicates that one was actually intended here ;)
Also, 'sm' should probably be spelled out as 'state machine'.
