* IPC_GEN_PHONE_RES has shared aseq (in the header), group, index and type (in the data)
* On this implementation, we just check aseq and command (group and index).
* aseq permits to identify the queued request and do what's wanted.
* It can be either call a function with the struct ipc_message_info,
* complete the request to RILJ (with or without an error),
* return to RILJ if there is an error in this response.
*
* It would have been possible to deal with group, index and type only and use
* callback functions. Though, what is currently being used is more a "standard"
* error catch system, that requires less code (no particular function), while
* it also permits using custom functions, when IPC_GEN_PHONE_RES code is
* request-specific.
*
* On a custom function, don't forget to get a clean new aseq if you're going to
* send some data to the modem, just liek this:
* aseq = ril_request_reg_id(reqGetToken(info->aseq));
