Thanks for looking at the smatch warnings! But I think you've taken
the wrong action on two of them. See below.

Hmm, I have a strong suspicion that the *indentation* was actually
correct, and your stylistic warning actually signals that the braces
are incorrect. See how the assignment to 'ps_state' is clobbered just
a few lines below; I suspect the failure to send a null packet is
supposed to mean we should exit this function immediately, and all
other cases are supposed to continue.
