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. As a nice side-effect this patch cuts ~1kB (x86-32) from the resulting code size: text data bss dec hex filename 53963 1244 237 55444 d894 drivers/ide/ide-core.o.before 52981 1244 237 54462 d4be drivers/ide/ide-core.o.after Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
