[PATCH v2 03/15] mfd: max14577: Rename state container to maxim_core

From: Krzysztof Kozlowski
Date: Fri Feb 07 2014 - 05:13:26 EST

This patch continues the preparation for adding support for max77836
device to existing max14577 driver.

The patch renames the struct "max14577" state container to "maxim_core".
This is only a rename-like patch, new code is not added.
