From 19c95d63e7768fe8909775188f5ef948f7ce324a Mon Sep 17 00:00:00 2001 From: Markus Pargmann Date: Mon, 21 Sep 2015 12:55:14 +0200 Subject: [PATCH] iio: bcm150: Remove i2c_client from private data i2c_client struct is now only used for debugging output. We can use the device struct as well so we can remove all struct i2c_client usage.
