My static checker complains that "devno" can be negative, meaning that we read before the start of the loop. I've looked at the code, and I think the warning is right. This come from /proc so it's root only or it would be quite a quite a serious bug. The call tree looks like this: proc_scsi_write() <- gets id and channel from simple_strtoul() -> scsi_add_single_device() <- calls shost->transportt->user_scan() -> ata_scsi_user_scan() -> ata_find_dev() Signed-off-by: NDan Carpenter <dan.carpenter@oracle.com> Signed-off-by: NTejun Heo <tj@kernel.org> Cc: stable@vger.kernel.org # all versions at this point
