From: Christof Schmitt <[email protected]> Adapt the change_queue_depth callback in zfcp for the new reason parameter. Simply pass each call back to the SCSI midlayer, there are no resource adjustments necessary for zfcp.
Signed-off-by: Christof Schmitt <[email protected]> Removes check for (depth <= default_depth) in case of SCSI_QDEPTH_RAMP_UP call back, not needed after added max_queue_depth per sdev.
