Alexandre Belloni fec9d3b1dc net: macb: initialize bp->queues[0].bp for at91rm9200
The macb driver currently crashes on at91rm9200 with the following trace:

Unable to handle kernel NULL pointer dereference at virtual address 00000014
[...]

[<c0574d70>] (kernel_init) from [<c00090e0>] (ret_from_fork+0x14/0x34)

Solve that by initializing bp->queues[0].bp in at91ether_init (as is done
in macb_init).

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.
