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/misc/da9063_onkey.ko | grep alias alias: platform:da9063-onkey After this patch: $ modinfo drivers/input/misc/da9063_onkey.ko | grep alias alias: platform:da9063-onkey alias: of:N*T*Cdlg,da9062-onkeyC* alias: of:N*T*Cdlg,da9062-onkey alias: of:N*T*Cdlg,da9063-onkeyC* alias: of:N*T*Cdlg,da9063-onkey Signed-off-by: Javier Martinez Canillas --- drivers/input/misc/da9063_onkey.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/input/misc/da9063_onkey.c b/drivers/input/misc/da9063_onkey.c index bb863e062b03..f0d0543562df 100644 --- a/drivers/input/misc/da9063_onkey.c +++ b/drivers/input/misc/da9063_onkey.c @@ -87,6 +87,7 @@ static const struct of_device_id da9063_compatible_reg_id_table[] = { { .compatible = "dlg,da9062-onkey", .data = &da9062_regs }, { }, }; +MODULE_DEVICE_TABLE(of, da9063_compatible_reg_id_table); static void da9063_poll_on(struct work_struct *work) { -- 2.7.4
