From e87bb7118c4f752de4616a7ab56c51ed3e7f6f53 Mon Sep 17 00:00:00 2001 From: Sebastian Andrzej Siewior Date: Thu, 6 Sep 2012 20:11:11 +0200 Subject: usb: gadget: move global vars from epautoconf into struct usb_gadget epautoconf has two global variables which count the endpoint number of last assigned endpoint. This patch removes the global variable and keeps it as per (UDC) gadget. While here, the ifdef is removed and now the in and outpoint are enumerated unconditionally. The dwc3 for instance supports 32 endpoints in total.
