Introduce two typedefs: pixel_read_t and pixel_write_t. It allows the compiler to check if the passed functions take the correct arguments. Such typedefs will help ensuring consistency across the code base in case of update of these prototypes. Rename input/output variable in a consistent way between read_line and write_line. A warn has been added in get_pixel_*_function to alert when an unsupported pixel format is requested. As those formats are checked before atomic_update callbacks, it should never happen. Document for those typedefs.

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 reStructuredText 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.
