Subject: [PATCH 15/24] ccs: Don't change the I²C address just for software reset
Date: Mon, 7 Dec 2020 23:15:21 +0200 [thread overview]
Message-ID: <20201207211530.21180-16-sakari.ailus@linux.intel.com> (raw)
In-Reply-To: <20201207211530.21180-1-sakari.ailus@linux.intel.com>
The sensor's address was changed before resetting and changing the
address again. Don't do it before reset as it's useless.
