As a side effect, a few error cases are fixed. If of_iomap() of sdma_regs failed, no error code was returned. Fixed to return -ENOMEM similar to of_iomap() fail of regs. If sysfs_create_group() or register_netdev() failed, lp->phy_node was not released. Finally, the order in remove function is corrected to be reverse order of what is done in probe, i.e. calling temac_mdio_teardown() last, so we unregister the netdev that most likely is using the mdio_bus first.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
