Use the V4L2 subdev active state API to store the active format. This simplifies the driver not only by dropping the state stored in the imx7_csi structure, but also by replacing the manual lock with the state lock. The is_streaming field is now protected by the active state lock, either explicitly in .s_stream(), where the active state is locked manually, or implicitly in .set_fmt(), which is called with the state locked.

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.
