It took more time than I originally anticipated, as I had to setup a way to test it here with some DVB-T devices, but I reviewed the code and tested it. I'm placing the patches I picked at this series: https://lore.kernel.org/lkml/53558de2b5c4f4ee6bfcfbe34e27071c2d0073d5.1684000646.git.mchehab@xxxxxxxxxx/T/#t They seemed to work fine. I tested using two devices: USB ID 2013:0246 PCTV Systems PCTV 74E USB ID 2040:5200 Hauppauge NovaT 500Stick The second one has two DVB-T independent devices on it. I did some tests of removing and re-inserting them with the devices closed and with the device opened and streamed. I didn't find any regressions. I didn't try to use kmemleak or KASAN to detect UAF conditions, though. Regards, Mauro
