From 35fcf02f801ba5358316113d0b94c541b9e39e84 Mon Sep 17 00:00:00 2001 From: Heikki Krogerus Date: Thu, 24 May 2018 11:18:24 +0300 Subject: [PATCH] usb: roles: intel_xhci: Always allow user control Trying to determine the USB port type with this mux is very difficult. To simplify the situation, always allow user control, even if the port is USB Type-C port.
