This is a note to let you know that I've just added the patch titled media: atomisp: Only set default_run_mode on first open of a stream/asd to the 6.1-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: media-atomisp-only-set-default_run_mode-on-first-ope.patch and it can be found in the queue-6.1 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 2bd0cd421bec9ea5cbd93c154f757e711b2c6680 Author: Hans de Goede <hdegoede@xxxxxxxxxx> Date: Wed Dec 28 23:11:47 2022 +0100 media: atomisp: Only set default_run_mode on first open of a stream/asd [ Upstream commit 60ec70a71a9f9975a5d2dd4a7d97c20da0e41976 ] Calling v4l2_ctrl_s_ctrl(asd->run_mode, pipe->default_run_mode) when the stream is already active (through another /dev/video# node) causes the stream to stop. Move the call to set the default run-mode so that it is only done on the first open of one of the 4 /dev/video# nodes of one of the 2 streams (atomisp-sub-devices / asd-s).
