From 511cb17448d95e4277451cdee882e72b6a9a3099 Mon Sep 17 00:00:00 2001 From: Keerthy Date: Wed, 30 Aug 2017 14:59:10 +0530 Subject: [PATCH] mfd: tps65217: Introduce dependency on CONFIG_OF Currently the driver boots only via device tree hence add a dependency on CONFIG_OF. This leaves with a bunch of unused code so clean that up. This patch also makes use of probe_new function in place of the probe function so as to avoid passing i2c_device_id.
