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/char/hw_random/meson-rng.ko | grep alias alias: platform:meson-rng After this patch: $ modinfo drivers/char/hw_random/meson-rng.ko | grep alias alias: platform:meson-rng alias: of:N*T*Camlogic,meson-rngC* alias: of:N*T*Camlogic,meson-rng Signed-off-by: Javier Martinez Canillas Acked-by: Neil Armstrong Signed-off-by: Herbert Xu --- diff --git a/drivers/char/hw_random/meson-rng.c b/drivers/char/hw_random/meson-rng.c index 58bef39f72860..51864a509be7a 100644 --- a/drivers/char/hw_random/meson-rng.c +++ b/drivers/char/hw_random/meson-rng.c @@ -110,6 +110,7 @@ static const struct of_device_id meson_rng_of_match[] = { { .compatible = "amlogic,meson-rng", }, {}, }; +MODULE_DEVICE_TABLE(of, meson_rng_of_match); static struct platform_driver meson_rng_driver = { .probe = meson_rng_probe,
