Without this patch if scsi reset or scan is called new block devices are created which point to the same id and lun. For example: ZynqMP> scsi scan scsi_scan: if_type=2, devnum=0: sdhci@ff170000.blk, 6, 0 scsi_scan: if_type=2, devnum=0: ahci@fd0c0000.id1lun0, 2, 0 scsi_scan: if_type=2, devnum=0: ahci@fd0c0000.id1lun0, 2, 1 scsi_scan: if_type=2, devnum=0: ahci@fd0c0000.id1lun0, 2, 2 scsi_scan: if_type=2, devnum=0: ahci@fd0c0000.id1lun0, 2, 3 scsi_scan: if_type=2, devnum=0: ahci@fd0c0000.id1lun0, 2, 4 scanning bus for devices...
