libfdt: fix undefined behaviour in fdt_splice_()
libfdt: fix undefined behaviour in fdt_splice_()
Along the lines of commit d0b3ab0a0f46 ("libfdt: Fix undefined behaviour
in fdt_offset_ptr()"), fdt_splice_() similarly may not use pointer
arithmetic to do overflow checks. (The left side of the checks added by
d4c7c25c9ed1 ["libfdt: check for potential overrun in _fdt_splice()"]
doesn't really lend itself to similar replacement though.)
