From 29e52cf793ded6bece50de50e738596f94f07d9f Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Sun, 17 May 2009 19:12:22 +0200 Subject: ide: remove chipset field from hw_regs_t * Convert host drivers that still use hw_regs_t's chipset field to use the one in struct ide_port_info instead. * Move special handling of ide_pci chipset type from ide_hw_configure() to ide_init_port(). * Remove chipset field from hw_regs_t. While at it: - remove stale comment in delkin_cb.c There should be no functional changes caused by this patch.
