From bcf5104e27187b8441aa10714b2dbe49f154bc92 Mon Sep 17 00:00:00 2001 From: Brian Masney Date: Tue, 17 Jan 2017 04:24:54 -0500 Subject: [PATCH] staging: iio: isl29028: move failure logging into isl29028_set_als_scale() When isl29028_set_als_scale() fails, it was up to both callers to log the failure message. This patch moves the logging into isl29028_set_als_scale() to reduce the overall amount of code in the driver.
