You're right !

this is duplicated because the ofono atoms cannot be created at the same point
for the two modems :
for sim800, we must wait for an URC stating that channels have been created
whereas sim900 is much straightforward.
That's why i've splitted : one in post_sim (sim900) another in mux_ready_notify
(sim800).
