From a96b9121862bbd18e00c865d9516e0a98bb135ef Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Thu, 4 Feb 2010 20:56:54 +0100 Subject: w1: move omap_hdq's probe function to .devinit.text MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A pointer to omap_hdq_probe is passed to the core via platform_driver_register and so the function must not disappear when the .init sections are discarded. Otherwise (if also having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late. An alternative to this patch is using platform_driver_probe instead of platform_driver_register plus removing the pointer to the probe function from the struct platform_driver.
