mcb: Acquire reference to device in probe
mcb_probe() does not aqcuire a reference to the probed device but drops one when removing the device. As it is actually using the device, it should grab a reference via get_device(). This could lead to a panic found with a rmmod/modprobe stress test Signed-off-by: Johannes Thumshirn <jthumshirn@suse.de> Reported-by: Andreas Werner <andreas.werner@men.de> Tested-by: Andreas Werner <andreas.werner@men.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
