Subject: [PATCH 4.9 007/109] uas: Always apply US_FL_NO_ATA_1X quirk to Seagate devices
4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hans de Goede <hdegoede@...hat.com>
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.
