From aa21a28e9050e77a37728693cdb4efaca75e36fc Mon Sep 17 00:00:00 2001 From: Andrey Smirnov Date: Wed, 3 Apr 2019 00:03:20 -0700 Subject: [PATCH] iio: imx7d_adc: Add local struct device pointer in imx7d_adc_probe() Use a local "struct device *dev" in imx7d_adc_probe() for brevity. No functional change intended.
