led: gpio: Fix possible ZERO_SIZE_PTR pointer dereferencing error. Since we cannot make sure the 'pdata->num_leds' will always be none zero here, and then if it equals to zero, the kmemdup() will return ZERO_SIZE_PTR, which equals to ((void *)16). So this patch fix this with just doing the zero check before calling kmemdup(). Signed-off-by: Xiubo Li <Li.Xiubo@freescale.com> Signed-off-by: Bryan Wu <cooloney@gmail.com>
