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/media/platform/vsp1/vsp1.ko | grep alias alias: vsp1 After this patch: $ modinfo drivers/media/platform/vsp1/vsp1.ko | grep alias alias: vsp1 alias: of:N*T*Crenesas,vsp2C* alias: of:N*T*Crenesas,vsp2 alias: of:N*T*Crenesas,vsp1C* alias: of:N*T*Crenesas,vsp1 Signed-off-by: Javier Martinez Canillas Reviewed-by: Laurent Pinchart Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab --- diff --git a/drivers/media/platform/vsp1/vsp1_drv.c b/drivers/media/platform/vsp1/vsp1_drv.c index 57c713a4e1df..aa237b48ad55 100644 --- a/drivers/media/platform/vsp1/vsp1_drv.c +++ b/drivers/media/platform/vsp1/vsp1_drv.c @@ -770,6 +770,7 @@ static const struct of_device_id vsp1_of_match[] = { { .compatible = "renesas,vsp2" }, { }, }; +MODULE_DEVICE_TABLE(of, vsp1_of_match); static struct platform_driver vsp1_platform_driver = { .probe = vsp1_probe,
