Subject: [PATCH 3.18 20/26] usb: quirks: Add no-lpm quirk for KY-688 USB 3.1 Type-C Hub

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

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

From: Kai-Heng Feng <kai.heng.feng@...onical.com>

commit e43a12f1793ae1fe006e26fe9327a8840a92233c upstream.

KY-688 USB 3.1 Type-C Hub internally uses a Genesys Logic hub to connect
to Realtek r8153.

Similar to commit ("7496cfe5431f2 usb: quirks: Add no-lpm quirk for Moshi
USB to Ethernet Adapter"), no-lpm can make r8153 ethernet work.
