Issue found during code review. This bug has no impact as long as the ks8851_net structure is the first element of the ks8851_net_spi structure. As long as the offset to the ks8851_net struct is zero, the container_of() macro is subtracting 0 and therefore no damage done. But if the ks8851_net_spi struct is ever modified such that the ks8851_net struct within it is no longer the first element of the struct, then the bug would manifest itself and cause problems. struct ks8851_net is contained within ks8851_net_spi. ks is contained within kss. kss is the priv_data of the netdev structure.

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.
