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/power/reset/syscon-reboot-mode.ko | grep alias $ After this patch: $ modinfo drivers/power/reset/syscon-reboot-mode.ko | grep alias alias: of:N*T*Csyscon-reboot-modeC* alias: of:N*T*Csyscon-reboot-mode Signed-off-by: Javier Martinez Canillas --- drivers/power/reset/syscon-reboot-mode.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/power/reset/syscon-reboot-mode.c b/drivers/power/reset/syscon-reboot-mode.c index 1ecb51d67149..c8c371b285b1 100644 --- a/drivers/power/reset/syscon-reboot-mode.c +++ b/drivers/power/reset/syscon-reboot-mode.c @@ -74,6 +74,7 @@ static const struct of_device_id syscon_reboot_mode_of_match[] = { { .compatible = "syscon-reboot-mode" }, {} }; +MODULE_DEVICE_TABLE(of, syscon_reboot_mode_of_match); static struct platform_driver syscon_reboot_mode_driver = { .probe = syscon_reboot_mode_probe, -- 2.7.4
