/**
 * Samsung-RIL TODO:
 *
 * General:
 * - USSD codes
 * - SIM SMS I/O
 * - ipc_disp_icon_info: trace on RILJ & emulate RIl_REQUEST_SIGNAL_STRENGTH
 * - airplane mode: trace: sys nodes?
 * - look at /sys nodes for data and airplane
 * - fails at killall zygote? → airplane mode bug?
 * - gen phone res queue → apply to max functions
 * - DTMF burst queue + lock, DTMF_START lock
 *
 * Data-related:
 * - find a reliable way to configure data iface
 * - GPRS: IPC_GPRS_CALL_STATUS, LAST_DATA_CALL_FAIL_CAUSE
 * - check data with orange non-free ril: no gprs_ip_config
 * - data: use IPC_GPRS_CALL_STATUS with global token for possible fail or return anyway and store ip config global?
 * - update global fail cause in global after gprs_call_status, generic error on stored token
