When iterating through all endpoints using of_graph_get_next_endpoint(), the refcount of the returned endpoint node is incremented and the refcount of the node which is passed as previous endpoint is decremented. So the caller doesn't need to call of_node_put() for each iterated node except for error exit paths. Otherwise we get "OF: ERROR: Bad of_node_put() on ..." messages.

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.
