If 'irq_of_parse_and_map()' or 'of_address_to_resource()' fail, 'err' is known to be 0 at this point. So return -ENODEV instead in the first case and use 'of_iomap()' instead of the equivalent 'of_address_to_resource()/ioremap()' combinaison in the 2nd case. Doing so, the 'rsrc_regs' field of the 'emac_instance struct' becomes redundant and is removed. While at it, turn a 'err != 0' test into an equivalent 'err' to be more consistent.

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.
