From c2e13037e6794bd0d9de3f9ecabf5615f15c160b Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Thu, 4 Feb 2010 20:56:51 +0100 Subject: platform-drivers: move probe to .devinit.text in drivers/video A pointer to a probe callback 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.
