    scsi: dm: Unbind all scsi based block devices before new scan · f8f41ae6
    Michal Simek authored
    New scan should unbind all block devices not to be listed again.
    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...
