[PATCH 3.4 14/25] usb-storage: restrict bcdDevice range for Super Top in Cypress ATACB

From: Greg Kroah-Hartman
Date: Thu Feb 20 2014 - 20:12:51 EST


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

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

From: Alan Stern <stern@xxxxxxxxxxxxxxxxxxx>

commit a9c143c82608bee2a36410caa56d82cd86bdc7fa upstream.

The Cypress ATACB unusual-devs entry for the Super Top SATA bridge
causes problems. Although it was originally reported only for
bcdDevice = 0x160, its range was much larger. This resulted in a bug
report for bcdDevice 0x220, so the range was capped at 0x219. Now
Milan reports errors with bcdDevice 0x150.

Therefore this patch restricts the range to just 0x160.
