To simplify implementation of debugfs seq_file show handlers, the driver passes the pointer to the show function through the debugfs_create_file data pointer. This prevents using the pointer to pass driver private data to the show handler, and requires all handlers to use global variables to access private data. To prepare for the removal of global private data in the driver, rework the debugfs infrastructure to allow passing a private data pointer to show handlers. The price to pay is explicit removal of debugfs files to free the internally allocated memory. This is desirable anyway as debugfs entries should be removed when a component driver is unbound, otherwise crashes will occur due to access to freed memory when the components will be dynamically allocated instead of stored in global variables.

README
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.
