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/staging/fbtft/flexfb.ko | grep alias $ After this patch: $ modinfo drivers/staging/fbtft/flexfb.ko | grep alias alias: platform:flexpfb Signed-off-by: Javier Martinez Canillas <javier@xxxxxxxxxxxxxxx> --- drivers/staging/fbtft/flexfb.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/staging/fbtft/flexfb.c b/drivers/staging/fbtft/flexfb.c index 2dc5f9b6b47e..ded10718712b 100644 --- a/drivers/staging/fbtft/flexfb.c +++ b/drivers/staging/fbtft/flexfb.c @@ -830,6 +830,7 @@ static const struct platform_device_id flexfb_platform_ids[] = { { "flexpfb", 0 }, { }, }; +MODULE_DEVICE_TABLE(platform, flexfb_platform_ids); static struct platform_driver flexfb_platform_driver = { .driver = { -- 2.7.4 _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
