leds: lm3533: Use devm_led_classdev_register
Switch to resource-managed function devm_led_classdev_register instead of led_classdev_register and remove unneeded led_classdev_unregister. To be compatible with this change, remove an unnecessary label by replacing it with direct return statement. The Coccinelle semantic patch used to make this change is as follows: //<smpl> @platform@ identifier p, probefn, removefn; @@ struct platform_driver p = { .probe = probefn, .remove = removefn, }; @prb@ identifier platform.probefn, pdev; expression e; @@ probefn(struct platform_device *pdev, ...) { ... e = - led_classdev_register + devm_led_classdev_register (...); ... ?- led_classdev_unregister(...); ... } @remove depends on prb@ identifier platform.removefn; @@ removefn(...) { ... ?- led_classdev_unregister(...); ... } //</smpl> Signed-off-by: Amitoj Kaur Chawla <amitoj1606@gmail.com> Signed-off-by: Jacek Anaszewski <j.anaszewski@samsung.com>
