Subject: usb: typec: ucsi: acpi: Implement resume callback
From: Heikki Krogerus <heikki.krogerus@xxxxxxxxxxxxxxx>
commit 4e3a50293c2b21961f02e1afa2f17d3a1a90c7c8 upstream.
The ACPI driver needs to resume the interface by calling
ucsi_resume(). Otherwise we may fail to detect connections
and disconnections that happen while the system is
suspended.
