NAME
       __shost_for_each_device - iterate over all devices of a host (UNLOCKED)

SYNOPSIS
       __shost_for_each_device(sdev, shost);

ARGUMENTS
       sdev
	   the struct scsi_device to use as a cursor

       shost
	   the struct scsi_host to iterate over

DESCRIPTION
       Iterator that returns each device attached to shost. It does _not_ take a reference on the scsi_device, so the whole loop must be protected
       by shost->host_lock.

NOTE
       The only reason to use this is because you need to access the device list in interrupt context. Otherwise you really want to use
       shost_for_each_device instead.
