The media.h public header is very messy. It mixes legacy and 'new' defines and it is not easy to figure out what should and what shouldn't be used. It also contains confusing comment that are either out of date or completely uninteresting for anyone that needs to use this header. The patch groups all entity functions together, including the 'old' defines based on the old range base. The reader just wants to know about the available functions and doesn't care about what range is used. All legacy defines are moved to the end of the header, so it is easier to locate them and just ignore them. The legacy structs in the struct media_entity_desc are put under also a much more effective signal to the reader that they shouldn't be used compared to the old method of relying on '#if 1' followed by a comment. The unused MEDIA_INTF_T_ALSA_* defines are also moved to the end of the header in the legacy area. They are also dropped from intf_type() in media-entity.c. All defines are also aligned at the same tab making the header easier to read.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
