From 3ef3b43d5633d30fa3f033f62094ec2e9c5b8376 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Wed, 31 May 2006 18:27:30 +0900 Subject: [PATCH] libata-hp-prep: implement ata_dev_init() Move initialization of struct ata_device into ata_dev_init() in preparation for hotplug. This patch calls ata_dev_init() from ata_host_init() and thus makes no functional difference.
