Subject[PATCH 4.14 014/323] USB: Add LPM quirk for Lenovo ThinkPad USB-C Dock Gen2 Ethernet
Date
From: Kai-Heng Feng <kai.heng.feng@canonical.com>

commit 8f23fe35ff1e5491b4d279323a8209a31f03ae65 upstream.

This is another branded 8153 device that doesn't work well with LPM
enabled:
[ 400.597506] r8152 5-1.1:1.0 enx482ae3a2a6f0: Tx status -71

So disable LPM to resolve the issue.
