From: Lior Amsalem <redacted> Date: Tue, 30 Jun 2015 16:09:49 +0200 Subject: ata: pmp: add quirk for Marvell 4140 SATA PMP From: Lior Amsalem <redacted> 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.
