struct sergensio *gensio_to_sergensio(struct gensio *io);

bool sergensio_is_client(struct sergensio *serio);

gensio_to_sergensio return the sergensio object for a gensio.  It returns NULL if there is no sergensio for the gensio.  Note that this may be a sergensio object for a child of the passed in gensio.  If the passed in gensio is not a sergensio, it will search through the children for a gensio that is also a sergensio.  This way, say, if you have an conacc gensio running over a serialdev, and you receive an serial event, you can just call gensio_to_sergensio for the passed in object and it will give you the sergensio you should be working with.  The first time this is called on a gensio it associates the sergensio with the passed in gensio.

sergensio_to_gensio returns the gensio for a given sergensio.  It cannot fail.  Note that this returns the gensio passed in to gensio_to_sergensio not the gensio directly associated with the passed in sergensio.

sergensio_get_user_data returns the gensio user data for the associated gensio.

sergensio_is_client returns true if the sergensio a client or false if it is a server.
