From b3226f961aa91eb94971939400c7506e7dcc86c0 Mon Sep 17 00:00:00 2001 From: Antti Palosaari Date: Tue, 24 Mar 2015 09:40:58 -0300 Subject: [media] ts2020: do not use i2c_transfer() on sleep() There is no need to use bulk i2c_transfer() to write single register. Use write register function instead.
