Title
scsi: xen: scsiback: Fix potential memory leak in scsiback_remove()
Summary
In the Linux kernel, the following vulnerability has been resolved: scsi: xen: scsiback: Fix potential memory leak in scsiback_remove() Memory allocated for struct vscsiblk_info in scsiback_probe() is not freed in scsiback_remove() leading to potential memory leaks on remove, as well as in the scsiback_probe() error paths. Fix that by freeing it in scsiback_remove().
