[PATCH 4.19 006/110] usb: dwc3: core: Clean up ULPI device

[Greg Kroah-Hartman]

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

------------------

From: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>

commit 08fd9a82fda86529bb2f2af3c2f7cb657b4d3066 upstream.

If dwc3_core_init_mode() fails with deferred probe,
next probe fails on sysfs with

sysfs: cannot create duplicate filename '/devices/pci0000:00/0000:00:11.0/dwc3.0.auto/dwc3.0.auto.ulpi'

To avoid this failure, clean up ULPI device.
