So user-space can't match the registered device with the corresponding module. Export the module alias information using the MODULE_DEVICE_TABLE() macro. Before this patch: $ modinfo drivers/mfd/fsl-imx25-tsadc.ko | grep alias alias: platform:mx25-tsadc After this patch: $ modinfo drivers/mfd/fsl-imx25-tsadc.ko | grep alias alias: platform:mx25-tsadc alias: of:N*T*Cfsl,imx25-tsadcC* alias: of:N*T*Cfsl,imx25-tsadc Signed-off-by: Javier Martinez Canillas --- drivers/mfd/fsl-imx25-tsadc.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/mfd/fsl-imx25-tsadc.c b/drivers/mfd/fsl-imx25-tsadc.c index 77b2675cf8f5..ac430a396a89 100644 --- a/drivers/mfd/fsl-imx25-tsadc.c +++ b/drivers/mfd/fsl-imx25-tsadc.c @@ -187,6 +187,7 @@ static const struct of_device_id mx25_tsadc_ids[] = { { .compatible = "fsl,imx25-tsadc" }, { /* Sentinel */ } }; +MODULE_DEVICE_TABLE(of, mx25_tsadc_ids); static struct platform_driver mx25_tsadc_driver = { .driver = { -- 2.7.4
