Subject: [PATCH] phy: tegra: xusb: Add missing tegra_xusb_port_unregister for usb2_port and ulpi_port
Git-commit: e024854048e733391b31fe5a398704b31b9af803
Patch-mainline: v6.4-rc1
References: git-fixes

The tegra_xusb_port_unregister should be called when usb2_port
and ulpi_port map fails in tegra_xusb_add_usb2_port() or in
tegra_xusb_add_ulpi_port(), fix it.
