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/power/supply/axp288_fuel_gauge.ko | grep alias $ After this patch: $ modinfo drivers/power/supply/axp288_fuel_gauge.ko | grep alias alias: platform:axp288_fuel_gauge Signed-off-by: Javier Martinez Canillas --- drivers/power/supply/axp288_fuel_gauge.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/power/supply/axp288_fuel_gauge.c b/drivers/power/supply/axp288_fuel_gauge.c index 5bdde692f724..539eb41504bb 100644 --- a/drivers/power/supply/axp288_fuel_gauge.c +++ b/drivers/power/supply/axp288_fuel_gauge.c @@ -1120,6 +1120,7 @@ static const struct platform_device_id axp288_fg_id_table[] = { { .name = DEV_NAME }, {}, }; +MODULE_DEVICE_TABLE(platform, axp288_fg_id_table); static int axp288_fuel_gauge_remove(struct platform_device *pdev) { -- 2.7.4
