Message

As discussed in the thread "Driver for something that's neither a
device nor an interface driver?", here's a patchset that makes it
possible for device drivers to extend the generic device driver.

An example usage is provided in the shape of a driver that allows
changing the charge type of an Apple MFi device to be fast.

Bastien Nocera (5):
  USB: Export generic USB device driver functions
  USB: Make it possible to "subclass" usb_device_driver
  USB: Implement usb_device_match_id()
  USB: Select better matching USB drivers when available
  USB: Add driver to control USB fast charge for iOS devices
