hi all:
below patch introduce unbind and rebind interfaces during usb reset

If a driver claims additional interfaces, the
claim may fail because the old binding instance may still own the
additional interface when the new

hi Alan:
I originally tried using usb_reset_device, and it caused a deadlock:
Unplug the HID device.
I/O error occurs. hid_io_error schedules reset_work.
The reset_work callback routine is hid_reset. It calls
usb_reset_device.
The reset fails

Okay. It's true that this issue is only tangentially related to the
main point of the patch. It could be removed

Hi Felipe Alan,
It is the follow-up for:
http://www.spinics.net/lists/linux-usb/msg112193.html
This patchset adds reset API at usb_gadget_driver, the UDC driver
can call it at bus_reset handler instead of calling disconnect.
The benefits of this patchset are:
- We can let the gadget driver do
Adding reset API for UDC bus reset handler is useful for below
two issues.
Current disconnect API at usb_gadget_driver is also invoked at
udc's bus reset handler, but the document says it is invoked when
the host is disconnected.
Besides, we may expect the gadget_driver to do different things

We have moved usb_gadget_disconnect to individual gadget driver's
disconnect, besides, it is suitable to call gadget driver's disconnect
before stopping udc, so using udc-driver-disconnect instead of
usb_gadget_disconnect at soft disconnect.

The usb_gadget_disconnect will be called at individual gadget
driver's disconnect, so delete it at udc core.

These are just programming registers in the chip, and I see no reason
to not keep these in the driver with real code.
