[SCSI] sd: Quiesce mode sense error messages
Messages about discovered disk properties are only printed once unless they are found to have changed. Errors encountered during mode sense, however, are printed every time we revalidate. Quiesce mode sense errors so they are only printed during the first scan. [jejb: checkpatch fixes] Bugzilla: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=733565 Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
