      [SCSI] sd: Add runtime pm in the sd_check_events() · 4e2247b2
      Lan Tianyu authored
      The sd_check_event() will be called periodly even when the device is in the
      suspended status to check media event. The scsi_test_unit_ready() in the
      sd_check_event() will issue scsi cmd request. Issuing scsi request when the
      device is in the suspeneded status will cause problem. For example, when a usb
      flash disk in the suspended status, scsi_test_unit_ready() issues a scsi
      request. The request will be returned as failed because the usb device is not
      active. The patch adds scsi_autopm_get_device() and scsi_autopm_put_device()
      around scsi_test_unit_ready() in the sd_check_event() to resolve such problem.
