Since dev->req_seq value is initialized from "reg" property of fdt node, there is posibility, that address value contained in fdt is greater than INT_MAX, and then value in dev->req_seq is negative which led to probe() fail.
This patch fix this problem by ensuring that req_seq is positive, unless it's one of errno codes.
