From 53d7d8139f652f87e1d9aa877007e757d08fc59e Mon Sep 17 00:00:00 2001 From: Akinobu Mita Date: Tue, 13 Jun 2017 00:05:08 +0900 Subject: [PATCH] iio: light: tcs3472: fix ATIME register write The integration time is controlled by the ATIME register only. However, this register is written by i2c_smbus_write_word_data() in write_raw(). We actually don't need to write a subsequent register. So just use i2c_smbus_write_byte_data() instead.
