fcup-smsend[mult]: fix buglet in K&R C NULL pointer passing The only 100% safe way to pass a NULL pointer as a function argument in K&R C is to cast 0 to a pointer type; failing to do so may cause mysterious bugs (invalid stack frames or garbage in argument registers) on 64-bit machines. This issue has already been fixed in most of FC host tools, but I just found some missed spots: passing of NULL UDH to PDU encoding functions in fcup-smsend[mult] in the case of single (not concatenated) SMS.

#include "types.h"

void
cmd_dieid()
{
	u32 addr;

	for (addr = 0xFFFEF010; addr <= 0xFFFEF016; addr += 2)
		printf("%08X: %04X\n", addr, *(volatile u16 *)addr);
}
