[sim-ready-v2 PATCH 0/3] ofono_sim_ready_notify

Hi all, Here is my 3rd stab at the ofono_sim_ready_notify(). I've generalized the role of ofono_sim_ready_notify(): it is expected after query_passwd_state returns the CME error 14 (SIM busy). It can be used before or after PIN/PUK checks. When ofono_sim_ready_notify() is invoked, it checks that the call is expected and if so, retries the query_passwd_state. The patches has now been tested with the PIN and PUK codes with mbm and the new isimodem sim driver by Jukka Saunamaki. The isimodem driver demonstrates also the case where PIN is disabled but SIM is not ready yet when oFono tries to initialize the modem. The isimodem driver tries to read some CPHS information in order to determine if the modem is ready. --Pekka
