From 583a2b2cd73c13a91b5f529466dec4d27716d226 Mon Sep 17 00:00:00 2001 From: Muhammad Falak R Wani Date: Sat, 5 Sep 2015 19:53:27 +0530 Subject: [PATCH] leds: leds-ot200: Use devm_led_classdev_register Use resource-managed function devm_led_classdev_register instead of led_classdev_register to make the error path simpler. The goto is replaced with direct return, unneeded label err is dropped. Also, remove redundant ot200_led_remove.
