Hi Greg, thanks for reviewing.

This output has probably gone through some processing before I got it,
so that's likely the cause. I don't have access to the original output,
sorry. If I need to fix something for a v2 I can try to re-format it to
add the indentation back in.

This isn't linked to a particular single commit, it fixes the same
problem in different parts of the code, introduced by different commits
over time. The starting point for the fix was the crash output in the
commit message but, for additional context, these are the original
commits that introduced the unguarded struct accesses:

  0cdd49a1d1a4 ("usb: Support USB 3.1 extended port status request")
  51e0a0120661 ("USB: Calculate USB 3.0 exit latencies for LPM.")
  25cd2882e2fc ("usb/xhci: Change how we indicate a host supports Link PM.")
  0299809be415 ("usb: core: Track SuperSpeed Plus GenXxY")
  ae8963adb4ad ("usb: Don't enable LPM if the exit latency is zero.")

Cheers,
Ricardo
