ipheth_carrier_set() is called from two locations. In ipheth_carrier_check_work(), its parameter 'dev' is set with container_of(work, ...) and can not be NULL. In ipheth_open(), dev is extracted from netdev_priv(net) and dereferenced before the call to ipheth_carrier_set(). The NULL pointer check of dev in ipheth_carrier_set() is therefore unnecessary and can be removed. Cc: Gustavo A. R.

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.
