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/thermal/tango_thermal.ko | grep alias $ After this patch: $ modinfo drivers/thermal/tango_thermal.ko | grep alias alias: of:N*T*Csigma,smp8758-thermalC* alias: of:N*T*Csigma,smp8758-thermal Signed-off-by: Javier Martinez Canillas --- drivers/thermal/tango_thermal.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/thermal/tango_thermal.c b/drivers/thermal/tango_thermal.c index 201304aeafeb..4e67795cb6ce 100644 --- a/drivers/thermal/tango_thermal.c +++ b/drivers/thermal/tango_thermal.c @@ -107,6 +107,7 @@ static const struct of_device_id tango_sensor_ids[] = { }, { /* sentinel */ } }; +MODULE_DEVICE_TABLE(of, tango_sensor_ids); static struct platform_driver tango_thermal_driver = { .probe = tango_thermal_probe, -- 2.7.4
