ASoC: imx-sgtl5000: return E_PROBE_DEFER if ssi/codec not found
If the ssi or codec drivers are not loaded (for instance, because spi or i2c bus drivers are not loaded), returning -EINVAL will for people to unload and then reload the module to get sound working. Returning E_PROBE_DEFER will mitigate this. Signed-off-by: Arnaud Patard <arnaud.patard@rtp-net.org> Signed-off-by: Mark Brown <broonie@linaro.org>
