Subject: net: move meth's probe function to .devinit.text
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=dd93667711761362b393cfbd5959bb11aa1fa80d;p=deliverable%2Flinux.git

net: move meth's probe function to .devinit.text

A pointer to meth_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.
