From a1932edf8baaf2b09ad72b119c1f9749ad4397f2 Mon Sep 17 00:00:00 2001 From: "Kim, Milo" Date: Wed, 2 Jan 2013 22:28:12 -0800 Subject: leds-lp8788: fix a parent device in _probe() The lp8788-keyled is a platform driver of lp8788-mfd. The platform device is allocated when mfd_add_devices() is called in lp8788-mfd. On the other hand, 'lp->dev' is the i2c client device. Therefore, this 'platform_device' is a proper parent device in case of resource managed mem alloc, registering led device and device kernel messages.
