Subject: usb: typec: ucsi: acpi: Always decode connector change information
From: Benjamin Berg <bberg@xxxxxxxxxx>
commit 47ea2929d58c35598e681212311d35b240c373ce upstream.
Normal commands may be reporting that a connector has changed. Always
call the usci_connector_change handler and let it take care of
scheduling the work when needed.
Doing this makes the ACPI code path identical to the CCG one.
