unbind/bind w1-gpio with device tree produce a crash

If w1-gpio is probed via device-tree configuration, pdata is allocated via devm_kzalloc. When the device is unbind (and bind later) the allocated memory of pdate is freed - but it will not be allocacted again. static int w1_gpio_probe(struct platform_device *pdev) struct w1_bus_master
