6.1-stable review patch. If anyone has any objections, please let me know.

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.
