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/devfreq/event/exynos-nocp.ko | grep alias $ After this patch: $ modinfo drivers/devfreq/event/exynos-nocp.ko | grep alias alias: of:N*T*Csamsung,exynos5420-nocpC* alias: of:N*T*Csamsung,exynos5420-nocp Signed-off-by: Javier Martinez Canillas --- drivers/devfreq/event/exynos-nocp.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/devfreq/event/exynos-nocp.c b/drivers/devfreq/event/exynos-nocp.c index 49e712aca0c1..5c3e7b11e8a6 100644 --- a/drivers/devfreq/event/exynos-nocp.c +++ b/drivers/devfreq/event/exynos-nocp.c @@ -190,6 +190,7 @@ static const struct of_device_id exynos_nocp_id_match[] = { { .compatible = "samsung,exynos5420-nocp", }, { /* sentinel */ }, }; +MODULE_DEVICE_TABLE(of, exynos_nocp_id_match); static struct regmap_config exynos_nocp_regmap_config = { .reg_bits = 32, -- 2.7.4
