Now that continuous mode is gone and we only have 1 /dev/video# node, the videobuf2 core guarantees that atomisp_css_[start|stop]() will only be called one at a time. So there is no need for atomisp_streaming_count() counts. When reqbufs has been done then the streams are guaranteed to be created, and streaming cannot be started without reqbufs so there is no need for atomisp_css_start() to check if it needs to create the streams. Use this to clean-up atomisp_css_[start|stop](). While at it also fix atomisp_css_start() not re-creating the streams on an error, breaking the guarantee that the streams are always there after a succesfull reqbufs call.

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.
