The m_can driver's suspend and resume functions (m_can_class_suspend() and m_can_class_resume()) make use of dev_get_drvdata() and assume that the drvdata is a pointer to the struct net_device. With upcoming conversion of the tcan4x5x driver to pm_runtime this assumption is no longer valid. As the suspend and resume functions actually need a struct m_can_classdev pointer, change the m_can_platform and the m_can_pci driver to hold a pointer to struct m_can_classdev instead, as the tcan4x5x driver already does.

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.
