| From | Uwe Kleine-König <> | Subject | [PATCH 13/58] move epson1355fb's probe function to .devinit.text | Date | Sat, 28 Mar 2009 00:26:34 +0100 |
| |
A pointer to epson1355fb_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.
