From bb82250fc45631bcac52af22328cb7c4dda3b763 Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Mon, 2 Jan 2017 13:03:27 -0300 Subject: [PATCH] backlight: da9052: Fix module autoload The driver has a platform device ID table with multiple device entries, each setting a different register address in its driver_data to control the WLED brightness. But the driver doesn't export these as aliases with MODULE_DEVICE_TABLE() when the driver is built as a module, instead it just has a single alias using MODULE_ALIAS("platform:da9052-backlight"). That is clearly wrong since there isn't a "da9052-backlight" in the platform device ID table, so if that device name is used, the device won't even match the driver. So instead of having a wrong alias, export the ones in the dev ID table. Before this patch: $ modinfo drivers/video/backlight/da9052_bl.ko | grep alias alias: platform:da9052-backlight After this patch: $ modinfo drivers/video/backlight/da9052_bl.ko | grep alias alias: platform:da9052-wled3 alias: platform:da9052-wled2 alias: platform:da9052-wled1 Signed-off-by: Javier Martinez Canillas Acked-by: Adam Thomson Acked-by: Jingoo Han Signed-off-by: Lee Jones --- drivers/video/backlight/da9052_bl.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/video/backlight/da9052_bl.c b/drivers/video/backlight/da9052_bl.c index fd2be417aa64..49035c12739a 100644 --- a/drivers/video/backlight/da9052_bl.c +++ b/drivers/video/backlight/da9052_bl.c @@ -167,6 +167,7 @@ static const struct platform_device_id da9052_wled_ids[] = { }, { }, }; +MODULE_DEVICE_TABLE(platform, da9052_wled_ids); static struct platform_driver da9052_wled_driver = { .probe = da9052_backlight_probe, @@ -182,4 +183,3 @@ module_platform_driver(da9052_wled_driver); MODULE_AUTHOR("David Dajun Chen "); MODULE_DESCRIPTION("Backlight driver for DA9052 PMIC"); MODULE_LICENSE("GPL"); -MODULE_ALIAS("platform:da9052-backlight"); -- 2.45.2
