Systems containing the Cavium HW RNG may have one device per NUMA node. A typical configuration is a 2-node NUMA system, which results in 2 RNG devices. The hwrng subsystem refuses (and rightly so) to register more than one device with he same name, so we get failure messages on these systems. Make the hwrng name unique by including the underlying device name. Also remove spaces from the name to make it possible to switch devices via the sysfs knobs.

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.
