From 931ee0dc5c69e8113233d21942681ab8fecde7f9 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Tue, 15 Jul 2008 21:21:47 +0200 Subject: [PATCH] ide: remove obsoleted "ide=" kernel parameters * Remove obsoleted "ide=" kernel parameters. * Remove no longer needed: - ide_setup() - parse_options() - __setup("", ...) - module_param(options, ...) * Use module_{init,exit}() for MODULE=y case and remove MODULE ifdef. * Make ide_*acpi* and ide_doubler variables static.
