[ Upstream commitfbed20280d] There is a potential execution path in which function of_find_compatible_node() returns NULL. In such a case, we end up having a NULL pointer dereference when accessing pointer *nfc_np* in function of_clk_get(). So, we better don't take any chances and fix this by null checking pointer *nfc_np* before calling of_clk_get().

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.
