Subject: net: move macsonic's probe function to .devinit.text
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=c9a73cdb772a487b2c59c2711ad8b10d58cbaca8;p=openwrt%2Fstaging%2Fblogic.git

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

A pointer to mac_sonic_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.

Various other functions that are called by mac_sonic_probe need to move
to .devinit.text, too.

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.
