From c97c6aca75fd5f718056fde7cff798b8cbdb07c0 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Wed, 23 Jul 2008 19:55:50 +0200 Subject: ide: pass hw_regs_t-s to ide_device_add[_all]() (take 3) * Add 'hw_regs_t **hws' argument to ide_device_add[_all]() and convert host drivers + ide_legacy_init_one() + ide_setup_pci_device[s]() to use it instead of calling ide_init_port_hw() directly. [ However if host has > 1 port we must still set hwif->chipset to hint consecutive ide_find_port() call that the previous slot is occupied. ] * Unexport ide_init_port_hw(). v2: * Use defines instead of hard-coded values in buddha.c, gayle.c and q40ide.c. (Suggested by Geert Uytterhoeven) * Better patch description. v3: * Fix build problem in ide-cs.c. (Noticed by Stephen Rothwell) There should be no functional changes caused by this patch.
