With some modems, the lock/unlock of the SIM-ME interface with +CSIM=1/0
command is followed by #QSS unsolicited messages. With the current
implementation, this messages are mistaken for SIM swap events and so the
modem is first dropped and then re-probed.
With this patch, the plugin takes into account the SIM-ME lock state when
parsing #QSS unsolicited, so that the QSS handler can correctly
elaborate the messages that are not related to SIM swap events.
Currently, when SIM hot swap fails in either mm-iface or plugin, the
ModemManager still opens ports context and prints a message saying that
SIM hot swap is supported and that it's waiting for SIM insertion,
instead of clearly saying that SIM hot swap is not working.
This patch:
1. introduces a new property MM_IFACE_MODEM_SIM_HOT_SWAP_CONFIGURED
which is FALSE by default and set to TRUE only when
setup_sim_hot_swap_finish() succeded.
2. subordinates the completion of SIM hot swap setup (in
mm-broadband-modem) and the related messages to the the value of
MM_IFACE_MODEM_SIM_HOT_SWAP_CONFIGURED
Finally, this patch replaces the MBIM's sim_hot_swap_on private property
with the new property MM_IFACE_MODEM_SIM_HOT_SWAP_CONFIGURED, since they have the
same meaning.
Commit acf101335 ("telit: port mm-broadband-modem-telit to use GTask")
ported most of the modem_set_current_bands code to use GTask, but missed
a few g_simple_async_report_error_in_idle calls, which potentially leads
to an incorrect G_TASK cast in modem_set_current_bands_finish.
When returning an enum value via g_task_return_int, some code assumes
the enum value is always non-negative and thus considers that a negative
value implies an error. This assumption could be invalidated if a
negative value is later added to the enum. To make it less error prone
to future changes, this patch modifies the code to check if the GError
argument to g_task_propagate_error is populated instead.
