commit 83967993f2320575c0ab27a80bf1d7535909c2f4 upstream.
Commit 372b2b0399fc ("media: v4l: vsp1: Release buffers in
start_streaming error path") introduced a helper to clean up buffers on
error paths, but inadvertently changed the code such that only the
output WPF buffers were cleaned, rather than the video node being
operated on.
Since then vsp1_video_cleanup_pipeline() has grown to perform both video
node cleanup, as well as pipeline cleanup. Split the implementation into
two distinct functions that perform the required work, so that each
video node can release its buffers correctly on streamoff. The pipe
cleanup that was performed in the vsp1_video_stop_streaming() (releasing
the pipe->dl) is moved to the function for clarity.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
