There is no point into hiding the -EINVAL error code in ERR_PTR from a dsa_get_ports function, simply get the "ports" node directly from within the dsa_parse_ports_dn function. This also has the effect to make the pdata and device tree handling code symmetrical inside _dsa_register_switch. At the same time, rename dsa_parse_ports_dn to dsa_parse_ports_of because _of is a more common suffix for device tree parsing functions.

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.
