[PATCH v7 05/10] mfd / platform: cros_ec: Rename config to a better name

From: Enric Balletbo i Serra
Date: Mon Sep 02 2019 - 05:53:31 EST


The cros-ec-dev is a multifunction device that now doesn't implement any
chardev communication interface. MFD_CROS_EC_CHARDEV doesn't look
a good name to describe that device and can cause confusion. Hence
rename it to CROS_EC_DEV.
