Subject: [PATCH 13/16] libata: re-initialize parameters before configuring
Date: Fri, 27 Jan 2006 00:39:12 +0900 [thread overview]
Message-ID: <11382899521388-git-send-email-htejun@gmail.com> (raw)
In-Reply-To: <1138289951261-git-send-email-htejun@gmail.com>
In ata_dev_configure(), reinitialize parameters before configuring.
This change is for revalidation and hotplug. As ata_dev_configure()
can be entered multiple times, parameters need to be reinitialized.
