When schemata parses the resource names it does not return an error if it detects incorrect resource names and fails quietly. This happens because for_each_enabled_rdt_resource(r) leaves "r" pointing beyond the end of the rdt_resources_all[] array, and the check for !r->name results in an out of bounds access. Split the resource parsing part into a helper function to avoid the issue.

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.
