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/input/touchscreen/fsl-imx25-tcq.ko | grep alias After this patch: $ modinfo drivers/input/touchscreen/fsl-imx25-tcq.ko | grep alias alias: of:N*T*Cfsl,imx25-tcqC* alias: of:N*T*Cfsl,imx25-tcq Signed-off-by: Javier Martinez Canillas --- drivers/input/touchscreen/fsl-imx25-tcq.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/input/touchscreen/fsl-imx25-tcq.c b/drivers/input/touchscreen/fsl-imx25-tcq.c index fe9877a6af9e..d50ee490c9cc 100644 --- a/drivers/input/touchscreen/fsl-imx25-tcq.c +++ b/drivers/input/touchscreen/fsl-imx25-tcq.c @@ -55,6 +55,7 @@ static const struct of_device_id mx25_tcq_ids[] = { { .compatible = "fsl,imx25-tcq", }, { /* Sentinel */ } }; +MODULE_DEVICE_TABLE(of, mx25_tcq_ids); #define TSC_4WIRE_PRE_INDEX 0 #define TSC_4WIRE_X_INDEX 1 -- 2.7.4
