From 23301b7f1b8910fb3ba84935edbf665808f53871 Mon Sep 17 00:00:00 2001 From: "Kim, Milo" Date: Wed, 12 Sep 2012 20:16:00 +0800 Subject: [PATCH] leds-lp5523: turn off the LED engines on unloading the driver The LP5523 has 3 engines which are used for running LED patterns. These engines should be off while unloading the driver. Obviously, LP5523 platform data are used for releasing the resource such like enable()/release_resource(), but these are not mandatory. Therefore this patch is required without the platform data dependency.
