From: Ben Hutchings
Date: Wed Feb 28 2018 - 10:34:55 EST


3.16.55-rc1 review patch. If anyone has any objections, please let me know.

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

From: Hans de Goede <hdegoede@xxxxxxxxxx>

commit 7fee72d5e8f1e7b8d8212e28291b1a0243ecf2f1 upstream.

We've been adding this as a quirk on a per device basis hoping that
newer disk enclosures would do better, but that has not happened,
so simply apply this quirk to all Seagate devices.
