spi: imx: Nothing to do in setupxfer when transfer is NULL
When the spi_transfer given in spi_imx_setupxfer is NULL then we have nothing to do. Bail out early in this case so that we do not have to test for t != NULL multiple times later. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Mark Brown <broonie@kernel.org>
