[PATCH 0/8] USB: serial: fix interface URB leaks and use-after-free

[Johan Hovold <johan@kernel.org>]

This series fixes a number of issues where resources were not properly
released on probe errors. Typically, URBs allocated and submitted in an
attach callback were never unlinked or released in a matching release
callback. This could lead to memory leaks and use-after-free bugs as
we could end up with unbound interfaces with active URBs.

Included is also a couple of minor fixes and clean ups of the keyspan
driver, and a fix of how we deal with minor-number exhaustion in core.
