From: Tejun Heo Date: Mon, 6 Aug 2007 09:36:23 +0000 (+0900) Subject: libata-link: update ata_scsi_error() to handle PMP links X-Git-Tag: v2.6.24-rc1~1391^2~107 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=cf1b86c8ab41fe2b2a2eb59c9a2ea9a7e463653a;p=karo-tx-linux.git libata-link: update ata_scsi_error() to handle PMP links Update ata_scsi_error() to handle PMP links. As error conditions can occur on both host and PMP links, __ata_port_for_each_link() is used.
