From eb0be47dbbdca133b1b94adc564297f25176b3ab Mon Sep 17 00:00:00 2001 From: Patrik Sevallius Date: Tue, 20 Nov 2007 09:32:00 -0800 Subject: USB: usb peripheral controller driver oops avoidance I'm having problem with oopses when rebooting, if I modprobe g_serial and rmmod g_serial and do a reboot I get an oops in device_shutdown(). The reason seems to be that usb_gadget_unregister_driver() doesn't do enough cleanup. With this at91_udc patch I don't get the oops.
