Subject: [ 86/86] USB: usb-storage: unusual_devs update for Super TOP SATA bridge

3.4-stable review patch.  If anyone has any objections, please let me know.

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

From: Josh Boyer <jwboyer@...hat.com>

commit 18e03310b5caa6d11c1a8c61b982c37047693fba upstream.

The current entry in unusual_cypress.h for the Super TOP SATA bridge devices
seems to be causing corruption on newer revisions of this device.  This has
been reported in Arch Linux and Fedora.  The original patch was tested on
devices with bcdDevice of 1.60, whereas the newer devices report bcdDevice
as 2.20.  Limit the UNUSUAL_DEV entry to devices less than 2.20.

This fixes https://bugzilla.redhat.com/show_bug.cgi?id=909591
