Subject: [PATCH 01/19] serdev: Add id_table to serdev_device_driver
Date:   Tue, 29 May 2018 15:09:56 +0200
Message-Id: <20180529131014.18641-2-ricardo.ribalda@gmail.com>
In-Reply-To: <20180529131014.18641-1-ricardo.ribalda@gmail.com>
References: <20180529131014.18641-1-ricardo.ribalda@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Currently, serdev device driver can only be used with devices that are
nodes of a device tree, or are part of the ACPI table.

Id_table will be used for devices that are created at runtime or that
are not part of the device tree nor the ACPI table.
