From 74e04345dc7e111fd151923d2de32267f1aae321 Mon Sep 17 00:00:00 2001 From: Markus Pargmann Date: Wed, 12 Aug 2015 16:50:05 +0200 Subject: [PATCH] iio: bmg160: Remove i2c_client from data struct i2c_client variable is not really used anymore in the core driver. It is only used to get the device to make proper outputs. This patch replaces all i2c_client usage through direct usage of the device pointer.
