drivers/rtc/rtc-spear.c: fix use-after-free in spear_rtc_remove()

2012-07-16T16:04:44Z

commit 2a643893e50fde71d7ba84b5592ec61b467b9ab6 upstream. `config' is freed and is then used in the rtc_device_unregister() call, causing a kernel panic.

rtc/rtc-spear: call platform_set_drvdata() before registering rtc device

2012-03-23T23:58:39Z

rtc_device_register() calls rtc-spear routines internally. These routines call dev_get_drvdata() to get struct spear_rtc_config. Currently, platform_set_drvdata is called after rtc device is registered. This causes system to crash, as dev_get_drvdata returns NULL. For this we need to call platform_set_drvdata() before registering rtc device. This requires further cleanup, that leads to removal of dev_set_drvdata on rtc->dev, which was just not required at all. Also, we change the parameter to request_irq and pass pointer to config instead of pointer to rtc struct. This patch brings all above changes.

rtc: convert drivers/rtc/* to use module_platform_driver()

This patch converts the drivers in drivers/rtc/* to use the module_platform_driver() macro which makes the code smaller and a bit simpler.
