From e6d42f0e962390e956545aa282efb05a9d6a41d1 Mon Sep 17 00:00:00 2001 From: Satyam Sharma Date: Mon, 3 Sep 2007 01:37:31 +0530 Subject: [PATCH] USB: sisusbvga: Fix bug drivers/usb/misc/sisusbvga/sisusb.c: In function sisusb_open drivers/usb/misc/sisusbvga/sisusb.c:2444: warning: sisusb is used uninitialized in this function is a genuine bug (which will cause oops). We cannot use "sisusb" in error path for (!interface), because sisusb will itself be derived from "interface" later.
