From 68350a886e7df0269a14af888dd68be2ba9203ca Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 11 Jul 2016 13:34:55 +0900 Subject: [PATCH] scsi: remove current_cmnd field from struct scsi_device The field is only used by the 53c700 driver, so move it into the driver-private device data instead of having it in the common structure.
