Instead of using an integer to keep count of how many buffers have been handed over to the ISP (buffers_in_css) move buffers handed over to the ISP to a new buffers_in_css list_head so that we can easily loop over them. This removes the need for atomisp_flush_video_pipe() to loop over all buffers and then (ab)use the state to figure out if they were handed over to the ISP. Since the buffers are now always on a list when owned by the driver this also allows the buffer_done path on flush vs normal completion to be unified (both now need a list_del()) and this common code can now be factored out into a new atomisp_buffer_done() helper. This is a preparation patch for moving the driver over to the videobuf2 framework.

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.
