[PATCH v2 0/1] NET: mcan: Move runtime PM enable/disable to m_can_platform

[Patrik Flykt <patrik.flykt@linux.intel.com>]

        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.

Thanks,

        Patrik
