From d0b2a5b80317cae1249d84136c1ab9bc036c0917 Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Wed, 19 Oct 2016 17:32:33 -0300 Subject: [PATCH] dmaengine: fsl_raid: 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/dma/fsl_raid.ko | grep alias $ After this patch: $ modinfo drivers/dma/fsl_raid.ko | grep alias alias: of:N*T*Cfsl,raideng-v1.0C* alias: of:N*T*Cfsl,raideng-v1.0 Signed-off-by: Javier Martinez Canillas Signed-off-by: Vinod Koul --- drivers/dma/fsl_raid.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/dma/fsl_raid.c b/drivers/dma/fsl_raid.c index db2f9e1653a2..90d29f90acfb 100644 --- a/drivers/dma/fsl_raid.c +++ b/drivers/dma/fsl_raid.c @@ -881,6 +881,7 @@ static struct of_device_id fsl_re_ids[] = { { .compatible = "fsl,raideng-v1.0", }, {} }; +MODULE_DEVICE_TABLE(of, fsl_re_ids); static struct platform_driver fsl_re_driver = { .driver = {
