mdiobus_register will search for any mdiobus board info registered for the bus being registered. If found, it will probe devices on the bus. That device, if for example it is an ethernet switch, may then try to register an mdio bus. Thus we need to allow recursive calls to mdiobus_register. Holding the mdio_board_lock will cause a deadlock during this recursion. Release the lock and use list_for_each_entry_safe. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.

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.
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.
