[PATCH 5.11 26/31] USB: Add LPM quirk for Lenovo ThinkPad USB-C Dock Gen2 Ethernet
From: Greg Kroah-Hartman
Date: Wed May 05 2021 - 08:14:39 EST
From: Kai-Heng Feng <kai.heng.feng@xxxxxxxxxxxxx>
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.
