| From | Uwe Kleine-König <> | Subject | [PATCH 27/29] move vfb's probe function to .devinit.text | Date | Sat, 23 Jan 2010 21:35:35 +0100 |
| |
A pointer to vfb_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.
