Subject: [PATCH v4 11/16] platform/x86: intel_cht_int33fe: Register max17047 in its own function
Date: Wed, 22 May 2019 13:51:08 +0300
Message-ID: <20190522105113.11153-12-heikki.krogerus@linux.intel.com> (raw)
In-Reply-To: <20190522105113.11153-1-heikki.krogerus@linux.intel.com>

To make the probe function a bit more nicer looking, moving
the registration of max17047 to its own function.
