Hi, This is a preparatory patch for modifying PM enabling due to PCI based M_CAN devices. As the functionality is right now, adding a PCI based M_CAN driver causes the core PCI functionality to call pm_runtime_enable() from pci_pm_init() when the PCI device is added. When the device is added, it is registered with m_can_class_register(), which ends up calling pm_runtime_enable() once more and causes the kernel to log an angry 'Unbalanced pm_runtime_enable!' message, as dev->power.disable_depth has gone down to zero. To resolve this situation, I have added a patch that moves runtime PM enabling from m_can.c to the m_can_platform.c driver, which currently is the only driver that ends up enabling runtime PM.
