From 7f612f272ad8abe82411f368bfacf793b466e1b3 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Mon, 13 Oct 2008 21:39:40 +0200 Subject: [PATCH] ide: remove [ata_]select_t * Use 'drive->dn & 1' in ide_init_disk(). * remove [ata_]select_t. While at it: * Use ATA_DEVICE_OBS define in ide_port_init_devices_data().
