From 5e7f3a46690f7f6c9f2781c700ab4370874aa0e8 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Tue, 6 Jan 2009 17:20:56 +0100 Subject: ide: dynamic allocation of device structures Allocate device structures dynamically instead of having them embedded in ide_hwif_t: * Remove needless zeroing of port structure from ide_init_port_data(). * Add ide_hwif_t.devices[MAX_DRIVES] (table of pointers to the devices). * Add ide_port_{alloc,free}_devices() helpers and use them respectively in ide_{host,free}_alloc(). * Convert all users of ->drives[] to use ->devices[] instead. While at it: * Use drive->dn for the slave device check in scc_pata.c.
