3.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Meenakshi Venkataraman <meenakshi.venkatara...@intel.com>
commit 66a770729a5cdd24efed8afa5258f81232d8bba2 upstream.
Shadow registers in the device are meant to
allow the driver to update certain device
registers without needing to wake up all
components of the device. However, using
this feature in the device causes
communication between the driver and the
device to become unreliable, resulting in
host command timeouts.
Disable this feature by default till a fix is
available for the bug.
