patch "uas: Always apply US_FL_NO_ATA_1X quirk to Seagate devices" added to usb-linus

[gregkh]

This is a note to let you know that I've just added the patch titled

    uas: Always apply US_FL_NO_ATA_1X quirk to Seagate devices

to my usb git tree which can be found at
    git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git
in the usb-linus branch.

The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)

The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.

If you have any questions about this process, please let me know.

Subject: uas: Always apply US_FL_NO_ATA_1X quirk to Seagate devices

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.
