Analyze and fix the following issue in the Linux kernel code: USB: usb peripheral controller driver oops avoidance
Problem Details: 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. Signed-off-by: Patrik Seval...
