[PATCH 5.8 192/255] usb: host: xhci-tegra: otg usb2/usb3 port init

[Greg Kroah-Hartman]

From: JC Kuo <jckuo@xxxxxxxxxx>

commit 316a2868bc269be8c6e69ccc3a1f902a3f518eb9 upstream.

tegra_xusb_init_usb_phy() should initialize "otg_usb2_port" and
"otg_usb3_port" with -EINVAL because "0" is a valid value
represents usb2 port 0 or usb3 port 0.
