From 345b48307d6961183be77748fc0ae5dd660c91a8 Mon Sep 17 00:00:00 2001 From: Hartmut Knaack <knaack.h@gmx.de> Date: Sat, 25 Oct 2014 20:09:11 +0200 Subject: [PATCH] iio:humidity:si7020: cleanup read_raw and probe When reading temperature or humidity values, a shift of two bits to the right needs to be applied, and only for the humidity channel a mask of the lower 12 bits needs to be applied. This reduces code repetition. During probe, i2c_set_clientdata() was used, although its counterpart was not, so drop it.
