| Subject: ata: pmp: add quirk for Marvell 4140 SATA PMP |
| |
| 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. |
