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 6b63376722d9e1b915a2948e9b30f4ba2712e3f5 Mon Sep 17 00:00:00 2001 From: Amelie Delaunay Date: Fri, 16 Jul 2021 14:07:18 +0200 Subject: usb: typec: stusb160x: Don't block probing of consumer of "connector" nodes Similar as with tcpm this patch lets fw_devlink know not to wait on the fwnode to be populated as a struct device. Without this patch, USB functionality can be broken on some previously supported boards.
