If a streaming user closes the\ndevice after disconnect, stop_streaming() runs and dereferences the\nNULL s->udev:\n\n  airspy_stop_streaming()\n    airspy_ctrl_msg(s, CMD_RECEIVER_MODE, 0, 0, NULL, 0)\n      usb_sndctrlpipe(s->udev, 0)         /* NULL deref */\n    airspy_free_stream_bufs(s)\n      usb_free_coherent(s->udev, ...)     /* NULL deref */\n\nThe airspy driver uses vb2_fop_release() in its file_operations, so\nreplace video_unregister_device(&s->vdev) with\nvb2_video_unregister_device(&s->vdev) and move it before clearing\ns->udev. vb2_video_unregister_device() releases the vb2 queue, which\nsynchronously runs airspy_stop_streaming() if streaming is active, so\nthe URBs, coherent DMA stream buffers and the hardware stop control\nmessage all execute while s->udev is still valid.\n\nvb2_video_unregister_device() locks vdev->queue->lock (vb_queue_lock)\ninternally, and stop_streaming() locks v4l2_lock, so the previous outer\nmutex_lock(&s->vb_queue_lock) / mutex_lock(&s->v4l2_lock) pair around\nthe unregister sequence would self-deadlock and has been removed. A\nshort v4l2_lock critical section around s->udev = NULL remains so any\nioctl path that still holds the file descriptor sees coherent state.\n\nIssue identified by automated review of the INV-003 series at\nhttps://sashiko.dev/"
