Subject[PATCH 0/4] USB: serial: add support for multi-interface functions
Date
A single USB function can be implemented using a group of interfaces and
this is for example commonly used for Communication Class devices.

This series adds support for multi-interface functions to USB serial
core and exports an interface that allows drivers to claim a second
sibling interface. The interface could easily be extended to allow
claiming further interfaces if ever needed.

The final patch uses the new interface to properly claim both the
control and data interface of Maxlinear/Exar devices.
