The error handling is broken with this patch,

Have a look at the switch (priv->version) in setup_m_can_dev(), you free
the m_can_dev in case of error, but exit with -EINVAL in the beginning
of the function. setup_m_can_dev() should not free if it doesn't allocate.

The error handling in m_can_plat_probe() is broken, too. If
pm_runtime_get_sync(&pdev->dev) fails, you don't free the candev.
