From: Greg Kroah-Hartman
Date: Tue Jan 10 2017 - 10:11:27 EST


4.4-stable review patch. If anyone has any objections, please let me know.

------------------

From: Johan Hovold <johan@xxxxxxxxxx>

commit e35d6d7c4e6532a89732cf4bace0e910ee684c88 upstream.

Bind to the interface, but do not register any ports, after having
downloaded the firmware. The device will still disconnect and
re-enumerate, but this way we avoid an error messages from being logged
as part of the process:

io_ti: probe of 1-1.3:1.0 failed with error -5
