The videobuf2-core expects buffers to be put back in the queued state when the vb2 start_streaming callback fails. But the atomisp atomisp_flush_video_pipe() would unconditionally return them to the core in an error state. This triggers the following warning in the videobuf2-core: drivers/media/common/videobuf2/videobuf2-core.c:1652: /* * If done_list is not empty, then start_streaming() didn't call * vb2_buffer_done(vb, VB2_BUF_STATE_QUEUED) but STATE_ERROR or * STATE_DONE. */ WARN_ON(!list_empty(&q->done_list)); Fix this by adding a state argument to atomisp_flush_video_pipe() and use VB2_BUF_STATE_QUEUED as state when atomisp_start_streaming() fails.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
