[PATCH 4.14 16/25] usb: core: hub: disable autosuspend for TI TUSB8041

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

From: Flavio Suligoi <f.suligoi@asem.it>

commit 7171b0e261b17de96490adf053b8bb4b00061bcf upstream.

The Texas Instruments TUSB8041 has an autosuspend problem at high
temperature.

If there is not USB traffic, after a couple of ms, the device enters in
autosuspend mode. In this condition the external clock stops working, to
save energy. When the USB activity turns on, ther hub exits the
autosuspend state, the clock starts running again and all works fine.

At ambient temperature all works correctly, but at high temperature,
when the USB activity turns on, the external clock doesn't restart and
the hub disappears from the USB bus.

Disabling the autosuspend mode for this hub solves the issue.
