The original github source allowed for the cache-line-size property to be missing. Since recent firmwares also require this property, it makes sense to always require it in the driver as well. If the cache-line-size property is missing, then the driver probe should fail as no dev since the kernel and dt may be out of sync. The fix is to add a check for the return value of of_property_read_u32. Changes V2: 1. Add error message if cache-line-size is missing. 2. Simple check for non-zero return value from of_property_read_u32.

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.
