This is a note to let you know that I've just added the patch titled media: exynos4-is: don't rely on the v4l2_async_subdev internals to the 5.15-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-exynos4-is-don-t-rely-on-the-v4l2_async_subdev.patch and it can be found in the queue-5.15 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 55a58a2d859a9a1b9f978c7043eefd473d1cefc6 Author: Marek Szyprowski <m.szyprowski@xxxxxxxxxxx> Date: Fri Sep 23 11:42:01 2022 +0200 media: exynos4-is: don't rely on the v4l2_async_subdev internals [ Upstream commit f98a5c2e1c4396488c27274ba82afc11725a4bcc ] Commit 1f391df44607 ("media: v4l2-async: Use endpoints in __v4l2_async_nf_add_fwnode_remote()") changed the data that is stored in the v4l2_async_subdev internals from the fwnode pointer to the parent device to the fwnode pointer to the matched endpoint. This broke the sensor matching code, which relied on the particular fwnode data in the v4l2_async_subdev internals. Fix this by simply matching the v4l2_async_subdev pointer, which is already available there.
