Moin!

USB is the main way of communicating with the TI Nspire CX II calculators,
so supporting the controller in Linux is necessary to make the port
somewhat useful. While implementing support for the specific controller
model inside, I found and fixed various bugs in this driver. Most of them
are part of the original driver code already and are so severe, that I
seriously wonder whether anyone actually used this driver ever.

With this series applied and some CX II specific commits on top, the
driver works fine for both USB serial and ethernet here.

The CX II support patches build upon this series, to avoid bigger
reiterations I'll submit them once this series got some positive feedback.

Cheers,
Fabian
