Hi!
Between commits 7ddb58cb0eca and d2f38a3c6507, the kernel stops
loading on my devices.
On the kernel log I see such a trace:

    usb: typec: port-mapper: Convert to the component framework

    Instead of trying to keep track of the connections to the
    USB Type-C connectors separately, letting the component
    framework take care of that.

    From now on every USB Type-C connector will register itself
    as "aggregate" - component master - and anything that can be
    connected to it inside the system can then simply register
    itself as a generic component.

    The matching of the components and the connector shall rely
    on ACPI _PLD initially. Before registering itself as the
    aggregate, the connector will find all other ACPI devices
    that have matching _PLD crc hash with it (matching value in
    the pld_crc member of struct acpi_device), and add a
    component match entry for each one of them. Because only
    ACPI is supported for now, the driver shall only be build
    when ACPI is supported.

    This removes the need for the custom API that the driver
    exposed. The components and the connector can therefore
    exist completely independently of each other. The order in
    which they are registered, as well as are they modules or
    not, is now irrelevant.
