From a06955ae1ef2a942f18025d4fefceea2c638a76f Mon Sep 17 00:00:00 2001 From: Jean-Jacques Hiblot Date: Thu, 29 Nov 2018 10:52:41 +0100 Subject: [PATCH] usb: gadget: Do not call board_usb_xxx() directly in USB gadget drivers Add 2 functions to wrap the calls to board_usb_init() and board_usb_cleanup(). This is a preparatory work for DM support for UDC drivers (DM_USB_GADGET).
