Subject: [PATCHv4 05/10] mfd: ti-lmu: use of_device_get_match_data() helper
Date:   Fri, 30 Mar 2018 19:24:09 +0200
Message-Id: <20180330172414.26575-6-sebastian.reichel@collabora.co.uk>
In-Reply-To: <20180330172414.26575-1-sebastian.reichel@collabora.co.uk>
References: <20180330172414.26575-1-sebastian.reichel@collabora.co.uk>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Replace of_match_device() with of_device_get_match_data(), which
slightly decreases lines of code and allows to move the DT table
next to the I2C table.
