From 3495de733633d24ee97852080b737b436c110d6e Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Sun, 23 Sep 2007 13:19:53 +0900 Subject: [PATCH] libata-pmp: update ata_eh_reset() for PMP PMP always requires SRST to be enabled. Also, hardreset reports classification code from the first device when PMP is attached, not from the PMP. Update ata_eh_reset() such that followup softreset is performed if the controller is PMP capable and the host link is being reset.
