From: Andrey Korolyov <andrey@xxxxxxx>
This patch has been added to the v4.1 stable tree. If you have any
objections, please let us know.
===============
[ Upstream commit 591b6bb605785c12a21e8b07a08a277065b655a5 ]
Several legacy devices such as Geode-based Cisco ASA appliances
and DB800 development board do possess CS5536 IDE controller
with different PCI id than existing one. Using pata_generic is
not always feasible as at least DB800 requires MSR quirk from
pata_cs5536 to be used with vendor firmware.
