From 5c608d4dd49a4ffbedc85f8a89820173df12b111 Mon Sep 17 00:00:00 2001 From: Jeremy Fertic Date: Tue, 4 Dec 2018 18:49:00 -0700 Subject: [PATCH] Revert "Staging: iio: adt7316: Add an extra check for 'ret' equals to 0" This reverts commit 00426e99789357dbff7e719a092ce36a3ce49d94. i2c_smbus_read_byte() returns 0 when a byte with the value 0 is read from the device. This is a valid read so revert the check for 0.
