From aa12c1ab8bb21c9e83bcc92eb75928170f24e666 Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Wed, 23 Nov 2016 13:37:09 -0300 Subject: [PATCH] spi: jcore: Fix module autoload for OF registration 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/spi/spi-jcore.ko | grep alias alias: platform:jcore_spi After this patch: $ modinfo drivers/spi/spi-jcore.ko | grep alias alias: platform:jcore_spi alias: of:N*T*Cjcore,spi2C* alias: of:N*T*Cjcore,spi2 Signed-off-by: Javier Martinez Canillas Signed-off-by: Mark Brown --- drivers/spi/spi-jcore.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/spi/spi-jcore.c b/drivers/spi/spi-jcore.c index f8117b80fa22..cebfea5faa4b 100644 --- a/drivers/spi/spi-jcore.c +++ b/drivers/spi/spi-jcore.c @@ -214,6 +214,7 @@ static const struct of_device_id jcore_spi_of_match[] = { { .compatible = "jcore,spi2" }, {}, }; +MODULE_DEVICE_TABLE(of, jcore_spi_of_match); static struct platform_driver jcore_spi_driver = { .probe = jcore_spi_probe,
