This is a note to let you know that I've just added the patch titled

usb: typec: ucsi: acpi: Implement resume callback

to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch.

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 heikki.krogerus@linux.intel.com 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.
