Patch in this message
Subject[PATCH] move jazzsonic's probe function to .devinit.text
A pointer to jazz_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.

As noticed by Geert Uytterhoeven sonic_probe1 is called by
jazz_sonic_probe, so the former has 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.

Hi Geert and Ralf,

thanks for your feed-back.

@Geert: Did you notice this, or your compiler?
@Ralf: I assume that I can still add your ack after this additional change?

Best regards
