scsi_device_quiesce() and scsi_device_resume() are called during system-wide suspend and resume. scsi_device_quiesce() only succeeds for SCSI devices that are in one of the RUNNING, OFFLINE or TRANSPORT_OFFLINE states (see also scsi_set_device_state()). This patch avoids that the following warning is triggered when resuming a system for which quiescing a SCSI device failed: WARNING: CPU: 2 PID: 11303 at drivers/scsi/scsi_lib.c:2600 scsi_device_resume+0x4f/0x58 CPU: 2 PID: 11303 Comm: kworker/u8:70 Not tainted 5.0.0-rc1+ #50 Hardware name: LENOVO 80E3/Lancer 5B2, BIOS A2CN45WW(V2.13) 08/04/2016 Workqueue: events_unbound async_run_entry_fn Call Trace: scsi_dev_type_resume+0x2e/0x60 async_run_entry_fn+0x32/0xd8 process_one_work+0x1f4/0x420 worker_thread+0x28/0x3c0 kthread+0x118/0x130 ret_from_fork+0x22/0x40 Cc: Przemek Socha <soprwa@gmail.com> Reported-by:
