Subject: [PATCH v6 02/14] mfd: da9063: Replace mfd_add_devices with devm counterpart
Date:   Mon, 11 Jun 2018 13:58:39 +0200
Message-Id: <20180611115851.1987-2-marek.vasut+renesas@gmail.com>
In-Reply-To: <20180611115851.1987-1-marek.vasut+renesas@gmail.com>
References: <20180611115851.1987-1-marek.vasut+renesas@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Use devm_mfd_add_devices() instead of plain mfd_add_devices(), which
removes the need for da9063_device_exit() altogether and also for the
.remove callback in da9063-i2c.c .
