From c802672cd36cd063bfd54d54c8c34825ab5b2357 Mon Sep 17 00:00:00 2001 From: Tomoya MORINAGA Date: Thu, 12 Jan 2012 11:27:06 +0900 Subject: [PATCH] usb: gadget: pch_udc: Fix wrong return value ISSUE: If the return value of pch_udc_pcd_init() is False, the return value of this function is unsettled. Since pch_udc_pcd_init() always returns 0, there is not actually the issue. CAUSE: If pch_udc_pcd_init() is True, the variable, retval, is not set for an appropriate value.
