Subject[PATCH 01/19] serdev: Add id_table to serdev_device_driver
Date
Currently, serdev device driver can only be used with devices that are
nodes of a device tree, or are part of the ACPI table.

Id_table will be used for devices that are created at runtime or that
are not part of the device tree nor the ACPI table.
