Subject: [PATCH] uas: Always apply US_FL_NO_ATA_1X quirk to Seagate devices
Git-commit: 7fee72d5e8f1e7b8d8212e28291b1a0243ecf2f1
Patch-mainline: v4.15-rc3
References: bsc#1085539
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.
