riscv: Fixup static_obj() fail
When enable LOCKDEP, static_obj() will cause error. Because some __initdata static variables is before _stext: static int static_obj(const void *obj) { unsigned long start = (unsigned long) &_stext, end = (unsigned long) &_end, addr = (unsigned long) obj; /* * static variable? */ if ((addr >= start) && (addr < end)) return 1; [ 0.067192] INFO: trying to register non-static key. [ 0.067325] the code is fine but needs lockdep annotation. [ 0.067449] turning off the locking correctness validator.
