[NSWI004] Is it test error or knowledge error?

[Jura Pelc]

for test basic/stack_pointer I got following output.
$sp unexpectedly changed (0x800003e8 => 0x800003e8)

As far as I understand this test and stack I think that last line should
have != instead ==
ktest_assert(sp1 != sp2, "$sp unexpectedly changed (0x%x => 0x%x)", sp1, sp2
);

Is is this case or should I get back to drawing board and self-study.

original code in upstream

    uintptr_t sp1 = value;
    uintptr_t sp2 = value;
    sp1 = debug_get_stack_pointer();
    sp2 = debug_get_stack_pointer();

    dprintk("sp1 = %x\n", sp1);
    dprintk("sp2 = %x\n", sp2);

    ktest_assert_in_range("$sp must be in mainmem", sp1, 0x80000000,
0x80100000);
    ktest_assert(sp1 == sp2, "$sp unexpectedly changed (0x%x =>
0x%x)", sp1, sp2);
