Subject: [PATCH] Revert "Staging: iio: adt7316: Add an extra check for 'ret' equals to 0"
Date: Tue,  4 Dec 2018 18:49:00 -0700	[thread overview]
Message-ID: <20181205014900.4827-1-jeremyfertic@gmail.com> (raw)

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.
