From b4d5cf0bc8f9d39c0674c87c610d95d3445a3434 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Fri, 4 Dec 2015 00:57:58 +0100 Subject: [PATCH] usb: s3c-otg: Rename struct s3c_udc to dwc2_udc The driver is actually for the Designware DWC2 controller. This patch renames struct s3c_udc to struct dwc2_udc to make things more obvious and clear.
