Fix an overflow case in fdt_offset_ptr() detected by GCC 4.3.
Using Gcc 4.3 detected this problem: ../dtc/libfdt/fdt.c: In function 'fdt_next_tag': ../dtc/libfdt/fdt.c:82: error: assuming signed overflow does not occur when assuming that (X + c) < X is always false To fix the problem, treat the offset as an unsigned int. The problem report and proposed fix were provided by Steve Papacharalambous <stevep@freescale.com>. Signed-off-by: Jon Loeliger <jdl@freescale.com>
