fix-usb-gadget-udc-not-provoking-curlim-action.patch
When we are informed by UDC stuff that we have been enumerated as a gadget, we recorded the new current limit but then did nothing. It meant that on boot, the enumeration happened but we remained stuck at 100mA current limit. This patch provokes a call to the work queue to change the current limit and means that coldplugged USB to a PC now recognizes it can pull 500mA when enumerated.
