From 5cb3b9d7c7cf2ab2bffaeaddef49378b28ccea5d Mon Sep 17 00:00:00 2001 From: Mugunthan V N Date: Fri, 18 Nov 2016 11:06:13 +0530 Subject: [PATCH] drivers: usb: gadget: ether: consolidate global devices to single struct Consolidate the net device, usb eth device and gadget device struct to single struct and a single global variable so that the same can be passed as priv of ethernet driver.
