You need a space between the semicolon and the comment.

But why isn't this struct just embedded in the struct stfsm? I don't
like static instances like this, especially when they are dynamically
configured (as your comment notes). In the crazy even that we ever have
two of these FSMs on an SoC (can this happen?), you'll be introducing a
race on needlessly-shared data.

The same comment applies to your later structs stfsm_seq_read and
stfsm_seq_write.
