Hi Laurent, you pleased me very much, also for your quick reply. 1) The patch is exactly the same as final state of my debugging. I just succesfully probe it against uvc_video.c <https://elixir.bootlin.com/linux/v6.6-rc6/source/drivers/media/usb/uvc/uvc_video.c> source on my PC running Linux HP-Pro-A-MT 6.5.0-9-generic #9-Ubuntu SMP PREEMPT_DYNAMIC Sat Oct 7 01:35:40 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux with Newmine camera. /The patch also doesn't hurt my other UVC 1.0 camera, Genius Qcam 6000./ All my 6.5.0 uvc*.c files in uvc directory are clean of any other changes I used for tests before, only the path of one single line in one file is there now. Now I also carefully compare 6.5.0 uvc_video.c <https://elixir.bootlin.com/linux/v6.6-rc6/source/drivers/media/usb/uvc/uvc_video.c> original (before the patch) with currect Linux sources at https://elixir.bootlin.com/linux/v6.6-rc6/source/drivers/media/usb/uvc/uvc_video.c and also at https://github.com/torvalds/linux/blob/master/drivers/media/usb/uvc/uvc_video.c These are different only in few blank characters :)). I am not able to run last git 6.6 kernel just now, but I hope that my verification by 6.5.0 will be enough. If is necessery - let me now, I will try compile last kernel on different, dedicated computer. (I never work with such a big git project. I sometimes used other's ppa results.) 2) You can mention my name in linux git history, I will be glad. best regards Karel Janda 20. 10. 2023 0:24 od laurent.pinchart@xxxxxxxxxxxxxxxx: > --- > Karel, could you please test this patch ?
