Subject: [PATCH 06/16] libata-link: linkify EH action helpers
Date: Sun, 1 Jul 2007 19:05:59 +0900 [thread overview]
Message-ID: <11832843591259-git-send-email-htejun@gmail.com> (raw)
In-Reply-To: <11832843581399-git-send-email-htejun@gmail.com>
Make ata_eh_about_to_do() and ata_eh_done() deal with ata_link instead
of ata_port.
This patch introduces no behavior change.
