From 77c4400f2f0fd8384ab5cbe41d81ccc664896b2d Mon Sep 17 00:00:00 2001 From: Richard Zhao Date: Fri, 29 Jun 2012 17:48:53 +0800 Subject: USB: Chipidea: rename struct ci13xxx_udc_driver to struct ci13xxx_platform_data This patch rename struct ci13xxx_udc_driver and var with the type. ci13xxx_platform_data reflect it's passed from platfrom driver.
