[PATCH v2 0/3] net: usb: r8152: Fix lost config across deauthorize+authorize

This series fixes problems introduced by commit ec51fbd1b8a2 ("r8152:
add USB device driver for config selection") where the r8152 device
would stop functioning if you deauthorized it (by writing 0 to the
"authorized" field in sysfs) and then reauthorized it (by writing a
1).

In v1 this was just a single patch [1], but it's now a 3-patch series
and solves the problem in a much cleaner way, as suggested by Alan
Stern.

Since these three patches straddle the USB subsystem and the
networking subsystem then maintainers will (obviously) need to work
out a way for them to land. I don't have any strong suggestions here
so I'm happy to let the maintainers propose what they think will work
best.
