smsc95xx_read_reg() and smsc95xx_write_reg() call BUG_ON() if the struct usbnet pointer passed in is NULL. The functions have just been amended to dereference the pointer on entry. So the kernel now oopses if the pointer is NULL, eliminating the need for an explicit BUG_ON(). Signed-off-by: Lukas Wunner <lukas@wunner.de> Signed-off-by: David S. Miller <davem@davemloft.net>
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.
