From 609e9d88f277bfe83392595745cc3976d42125b2 Mon Sep 17 00:00:00 2001 From: Hartmut Knaack <knaack.h@gmx.de> Date: Tue, 28 Jul 2015 00:39:01 +0200 Subject: iio:adc:berlin2-adc: use short operator format Use augmented assignment to subtract the offset for negative temperature values. Specify the amount of private data to be allocated through devm_iio_device_alloc() with sizeof(*priv), as it is shorter and common practice in IIO.
