[PATCH v3] usb: quirks: Add no-lpm quirk for Moshi USB to Ethernet Adapter

From: Kai-Heng Feng
Date: Tue Aug 08 2017 - 05:51:37 EST


Moshi USB to Ethernet Adapter internally uses a Genesys Logic hub to
connect to Realtek r8153.

The Realtek r8153 ethernet does not work on the internal hub, no-lpm quirk
can make it work.

Since another r8153 dongle at my hand does not have the issue, so add
the quirk to the Genesys Logic hub instead.

v3: Update comment to reflect the quirk is for the hub.

v2: Clarify that the adapter uses a hub internally.
