From: Uwe Kleine-König Date: Fri, 27 Mar 2009 23:26:38 +0000 (+0100) Subject: leds: move h1940-leds's probe function to .devinit.text X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b0edba7ef89a64614e40023bf87ed5b402834e04;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git leds: move h1940-leds's probe function to .devinit.text A pointer to h1940leds_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.
