From: Lior Amsalem <alior@xxxxxxxxxxx>
3.4.111-rc1 review patch. If anyone has any objections, please let me know.
------------------
commit 945b47441d83d2392ac9f984e0267ad521f24268 upstream.
This commit adds the necessary quirk to make the Marvell 4140 SATA PMP
work properly. This PMP doesn't like SRST on port number 4 (the host
port) so this commit marks this port as not supporting SRST.
