spi: Fix possible ZERO_SIZE_PTR pointer dereferencing error. Since we cannot make sure the 'n' will always be none zero here, and then if either equal to zero, the kzalloc() will return ZERO_SIZE_PTR, which equals to ((void *)16). So this patch fix this with just doing the zero check before calling kzalloc(). Signed-off-by: Xiubo Li <Li.Xiubo@freescale.com> Signed-off-by: Mark Brown <broonie@kernel.org>
