Subject: [PATCH v3 1/4] usb: roles: intel_xhci: Always allow user control
Date: Thu, 24 May 2018 11:18:24 +0300	[thread overview]
Message-ID: <20180524081827.37861-2-heikki.krogerus@linux.intel.com> (raw)
In-Reply-To: <20180524081827.37861-1-heikki.krogerus@linux.intel.com>

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.
