If anyone has any objections, please let me know. ------------------ From: Javier Martinez Canillas [ Upstream commit 8f0d7daf53972da0004f7a5a4d938c85333db300 ] 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/iio/adc/fsl-imx25-gcq.ko | grep alias $ After this patch: $ modinfo drivers/iio/adc/fsl-imx25-gcq.ko | grep alias alias: of:N*T*Cfsl,imx25-gcqC* alias: of:N*T*Cfsl,imx25-gcq Signed-off-by: Javier Martinez Canillas Signed-off-by: Jonathan Cameron Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman --- drivers/iio/adc/fsl-imx25-gcq.c | 1 + 1 file changed, 1 insertion(+) --- a/drivers/iio/adc/fsl-imx25-gcq.c +++ b/drivers/iio/adc/fsl-imx25-gcq.c @@ -401,6 +401,7 @@ static const struct of_device_id mx25_gc { .compatible = "fsl,imx25-gcq", }, { /* Sentinel */ } }; +MODULE_DEVICE_TABLE(of, mx25_gcq_ids); static struct platform_driver mx25_gcq_driver = { .driver = {
