The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From 4e3a50293c2b21961f02e1afa2f17d3a1a90c7c8 Mon Sep 17 00:00:00 2001 From: Heikki Krogerus Date: Fri, 7 Oct 2022 13:09:51 +0300 Subject: usb: typec: ucsi: acpi: Implement resume callback 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.
