NAME
       scsi_device_get - get an additional reference to a scsi_device

SYNOPSIS
       int scsi_device_get(struct scsi_device * sdev);

ARGUMENTS
       sdev
           device to get a reference to

DESCRIPTION
       Gets a reference to the scsi_device and increments the use count of the underlying LLDD
       module. You must hold host_lock of the parent Scsi_Host or already have a reference when
       calling this.

       This will fail if a device is deleted or cancelled, or when the LLD module is in the
       process of being unloaded.
