Subject: usb: ulpi: Fix debugfs directory leak
From: Sean Anderson <sean.anderson@xxxxxxxx>
commit 3caf2b2ad7334ef35f55b95f3e1b138c6f77b368 upstream.
The ULPI per-device debugfs root is named after the ulpi device's
parent, but ulpi_unregister_interface tries to remove a debugfs
directory named after the ulpi device itself. This results in the
directory sticking around and preventing subsequent (deferred) probes
from succeeding. Change the directory name to match the ulpi device.
