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

usb: ulpi: Move of_node_put to ulpi_dev_release

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 092f45b13e51666fe8ecbf2d6cd247aa7e6c1f74 Mon Sep 17 00:00:00 2001 From: Sean Anderson sean.anderson@seco.com Date: Thu, 27 Jan 2022 14:00:02 -0500 Subject: usb: ulpi: Move of_node_put to ulpi_dev_release

Drivers are not unbound from the device when ulpi_unregister_interface is called. Move of_node-freeing code to ulpi_dev_release which is called only after all users are gone.
