priv->cbs is an array of priv->info->num_cbs_shapers elements of type
struct sja1105_cbs_entry which only get allocated if CONFIG_NET_SCH_CBS
is enabled.
However, sja1105_reload_cbs() is called from sja1105_static_config_reload()
which in turn is called for any of the items in sja1105_reset_reasons,
therefore during the normal runtime of the driver and not just from a
code path which can be triggered by the tc-cbs offload.
The sja1105_reload_cbs() function does not contain a check whether the
priv->cbs array is NULL or not, it just assumes it isn't and proceeds to
iterate through the credit-based shaper elements. This leads to a NULL
pointer dereference.
The solution is to return success if the priv->cbs array has not been
allocated, since sja1105_reload_cbs() has nothing to do.

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.
