[PATCH 1/2] power: charger-manager: regulator_get() never returns NULL.

From: Jonghwa Lee
Date: Tue Jun 25 2013 - 01:03:24 EST


This patch fixes return value checking of regulator_get() in charger-manager
driver. The API, regulator_get(), returns ERR_PTR() when it fails to get
regulator with given name, not NULL.
