This\nindicates that urb->context, which contains struct si470x_device\nobject, is freed when si470x_int_in_callback() is called.\n\nThe cause of this issue is that si470x_int_in_callback() is called for\nfreed urb.\n\nsi470x_usb_driver_probe() calls si470x_start_usb(), which then calls\nusb_submit_urb() and si470x_start().  If si470x_start_usb() fails,\nsi470x_usb_driver_probe() doesn't kill urb, but it just frees struct\nsi470x_device object, as depicted below:\n\nsi470x_usb_driver_probe()\n  ...\n  si470x_start_usb()\n    ...\n    usb_submit_urb()\n    retval = si470x_start()\n    return retval\n  if (retval < 0)\n    free struct si470x_device object, but don't kill urb\n\nThis patch fixes this issue by killing urb when si470x_start_usb()\nfails and urb is submitted.  If si470x_start_usb() fails and urb is\nnot submitted, i.e. submitting usb fails, it just frees struct\nsi470x_device object."
