From 2f3f1a261c0f4827bda86009f0059aefbe30ed11 Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Wed, 19 Oct 2016 18:06:24 -0300 Subject: PM / devfreq: rk3399_dmc: Fix module autoload If the driver is built as a module, autoload won't work because the module alias information is not filled. 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/rk3399_dmc.ko | grep alias $ After this patch: $ modinfo drivers/devfreq/rk3399_dmc.ko | grep alias alias: of:N*T*Crockchip,rk3399-dmcC* alias: of:N*T*Crockchip,rk3399-dmc Signed-off-by: Javier Martinez Canillas Signed-off-by: MyungJoo Ham --- drivers/devfreq/rk3399_dmc.c | 1 + 1 file changed, 1 insertion(+) (limited to 'drivers/devfreq') diff --git a/drivers/devfreq/rk3399_dmc.c b/drivers/devfreq/rk3399_dmc.c index e24b73d66659..77bd9d02e870 100644 --- a/drivers/devfreq/rk3399_dmc.c +++ b/drivers/devfreq/rk3399_dmc.c @@ -454,6 +454,7 @@ static const struct of_device_id rk3399dmc_devfreq_of_match[] = { { .compatible = "rockchip,rk3399-dmc" }, { }, }; +MODULE_DEVICE_TABLE(of, rk3399dmc_devfreq_of_match); static struct platform_driver rk3399_dmcfreq_driver = { .probe = rk3399_dmcfreq_probe, -- cgit v1.2.3-58-ga151
