usb: ulpi: Fix debugfs directory leak
commit3caf2b2ad7
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. Fixes:bd0a0a024f
