From cb26d236861ca6a3354f1623ae5b9c049fd2f972 Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Thu, 10 Sep 2020 18:32:30 +0100 Subject: iio:chemical:sgp30: Use local variable dev to simplify code This cleans up the code at bit, but is primarily here as a precusor to the next patch. I've only done this for the two functions which use the dev pointer repeatedly.
