I believe the consensus is that any device initialization function that
returns an error is simply ignored and skipped, which is what my patch does:
for (i = 0; i < num; i++) {
ret = tsec_initialize(bis, &tsecs[i]);
if (ret > 0)
count += ret;
}
I could have done "if (ret >= 0)", but that's less efficient.

But which error code? What if the first device returns -1, and the second
one returns -2?

That's what we do today.
