[PATCH] leds: leds-hp6xx: Use devm_led_classdev_register

From: Muhammad Falak R Wani
Date: Sat Sep 05 2015 - 15:50:25 EST


Use resource-managed function devm_led_classdev_register
instead of led_classdev_register to simplify error path.
An unnecessary check of ret is replaced with a direct return
Also, remove redundant hp6xxled_remove.
