When WWAN device wake from S3 deep, under thinkpad platform, WWAN would be disabled. This disable status could be checked by command 'nmcli r wwan' or 'rfkill list'. Issue analysis as below: When host resume from S3 deep, thinkpad_acpi driver would call hotkey_resume() function. Finnaly, it will use wan_get_status to check the current status of WWAN device. During this resume progress, wan_get_status would always return off even WWAN boot up completely. In patch V2, Hans said 'sw_state should be unchanged after a suspend/resume. It's better to drop the tpacpi_rfk_update_swstate call all together from the resume path'. And it's confimed by Lenovo that GWAN is no longer available from WHL generation because the design does not match with current pin control.
