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 57560ee95cb7f91cf0bc31d4ae8276e0dcfe17aa Mon Sep 17 00:00:00 2001 From: Martin Kepplinger Date: Wed, 14 Jul 2021 08:18:07 +0200 Subject: usb: typec: tipd: 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.
