Subject: auxdisplay: move cfag12864bfb's probe function to .devinit.text
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=57f1e87523bdb6c39659ead7c0f72eea9e520fbe;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

auxdisplay: move cfag12864bfb's probe function to .devinit.text

A pointer to cfag12864bfb_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.
