Subject: [PATCH 0/2] USB: serial: console: fix two use-after-free bugs

A recent clean-up patch of mine did more than intended and introduced
the potential for a use-after-free on disconnect under some very
specific circumstances. Fortunately those circumstances were not obscure
enough to prevent Andrey's fuzzing from triggering the bug.

While fixing this one I found a related issue through inspection which
dates back to 2006.
