This is a note to let you know that I've just added the patch titled media: imx: capture: Return -EPIPE from __capture_legacy_try_fmt() to the 5.4-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-imx-capture-return-epipe-from-__capture_legacy.patch and it can be found in the queue-5.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 3d439fafe684148ee6633bd9de2957ec1b06a11b Author: Laurent Pinchart <laurent.pinchart@xxxxxxxxxxxxxxxx> Date: Mon Feb 15 05:26:47 2021 +0100 media: imx: capture: Return -EPIPE from __capture_legacy_try_fmt() [ Upstream commit cc271b6754691af74d710b761eaf027e3743e243 ] The correct return code to report an invalid pipeline configuration is -EPIPE. Return it instead of -EINVAL from __capture_legacy_try_fmt() when the capture format doesn't match the media bus format of the connected subdev.
