From: Uwe Kleine-König Date: Thu, 4 Feb 2010 19:56:49 +0000 (+0100) Subject: platform-drivers: move probe to .devinit.text in arch/arm X-Git-Tag: v2.6.34-rc1~1^2~32 X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=91a99dfc6b57f2e956d10d41123234fad3399212;p=~shefty%2Frdma-dev.git platform-drivers: move probe to .devinit.text in arch/arm 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.
