From 48c3c1072651922ed153bcf0a33ea82cf20df390 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Wed, 23 Jul 2008 19:55:57 +0200 Subject: ide: add struct ide_host (take 3) * Add struct ide_host which keeps pointers to host's ports. * Add ide_host_alloc[_all]() and ide_host_remove() helpers. * Pass 'struct ide_host *host' instead of 'u8 *idx' to ide_device_add[_all]() and rename it to ide_host_register[_all](). * Convert host drivers and core code to use struct ide_host. * Remove no longer needed ide_find_port(). * Make ide_find_port_slot() static. * Unexport ide_unregister(). v2: * Add missing 'struct ide_host *host' to macide.c. v3: * Fix build problem in pmac.c (s/ide_alloc_host/ide_host_alloc/) (Noticed by Stephen Rothwell).
