From 9f3b795a626ee79574595e06d1437fe0c7d51d29 Mon Sep 17 00:00:00 2001 From: Michał Mirosław Date: Fri, 1 Feb 2013 20:40:17 +0100 Subject: driver-core: constify data for class_find_device() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit All in-kernel users of class_find_device() don't really need mutable data for match callback. In two places (kernel/power/suspend_test.c, drivers/scsi/osd/osd_uld.c) this patch changes match callbacks to use const search data. The const is propagated to rtc_class_open() and power_supply_get_by_name() parameters. Note that there's a dev reference leak in suspend_test.c that's not touched in this patch.
