Since there can be multiple dsa switches stacked together but not all of devicetree nodes available at the time of calling dsa_dst_parse(), EPROBE_DEFER can be returned by it. When this happens, only the last dsa switch has to be deleted by dsa_dst_del_ds(), but not the whole list, because next time linux cames back to this function it will try to add only the last dsa switch which returned EPROBE_DEFER.

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.
