USB gadget stops working for me on n900, if I merge usb: gadget: bind UDC by name passed via usb_gadget_driver structure patch. commit 2284b29d3d9dd16490909962574d7f3fef83fd97 Author: Ruslan Bilovol Date: Mon Nov 23 09:56:35 2015 +0100 usb: gadget: bind UDC by name passed via usb_gadget_driver structure Introduce new 'udc_name' member to usb_gadget_driver structure. The 'udc_name' is a name of UDC that usb_gadget_driver should be bound to. If udc_name is NULL, it will be bound to any available UDC. Tested-by: Maxime Ripard Signed-off-by: Ruslan Bilovol Signed-off-by: Marek Szyprowski Tested-by: Peter Chen Signed-off-by: Felipe Balbi Patch is obvious enough... if there's someone who sets udc_name to NULL. Who is supposed to do that? (I have patch in my tree to make USB gadget work when it is not modular).
