Like other drivers, expose the ELD bytes via a control element so that user-space can parse it. For the simplicity, the code to register the ctl elements is refactored using an array. Also, since ELD ctl read copies the bytes also during disconnection, clear the ELD bytes at hot-unplug, in order to avoid the leak of the previous bogus ELD.

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.
