From 74e6ad583aa34a8de3ab3bc209256c3b53a1af4b Mon Sep 17 00:00:00 2001 From: Mathias Nyman Date: Mon, 21 May 2018 16:39:58 +0300 Subject: [PATCH] xhci: rename faked_port_index to hcd_portnum hcd_portnum is a better desctiption than faked_port_index, and is in line with the name the port structure uses.
