Subject[PATCH 4.19 70/79] r8152: add device id for Lenovo ThinkPad USB-C Dock Gen 2
Date
From: Kazutoshi Noguchi <noguchi.kazutosi@gmail.com>

[ Upstream commit b3060531979422d5bb18d80226f978910284dc70 ]

This device is sold as 'ThinkPad USB-C Dock Gen 2 (40AS)'.
Chipset is RTL8153 and works with r8152.
Without this, the generic cdc_ether grabs the device, and the device jam
connected networks up when the machine suspends.
