commitc15e1bdda4upstream. When the primary firmware node pointer is removed from a device (set to NULL) the secondary firmware node pointer, when it exists, is made the primary node for the device. However, the secondary firmware node pointer of the original primary firmware node is never cleared (set to NULL). To avoid situation where the secondary firmware node pointer is pointing to a non-existing object, clearing it properly when the primary node is removed from a device in set_primary_fwnode().

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.
