No, I'm afraid that means that the bisection is broken:

bisection log:  https://syzkaller.appspot.com/x/bisect.txt?x=140283ad700000

and yeah, looking at that log it looks like every single run has

  testing commit [...]
  run #0: crashed: KASAN: use-after-free Read in ath9k_hif_usb_rx_cb
  ...
  # git bisect good [...]

and you never saw a "bad" commit that didn't have the issue, so the
top-of-tree gets marked "good" (and I suspect you intentionally mark
the broken case "good" in order to find where it got fixed, so you're
using "git bisect" in a reverse way).

I didn't look closer, but it does seem to not reproduce very reliably,
maybe that is what confused the bot originally.
