Subject: [PATCH] ubimkvol: add support for `volume_id` parameter
Date: Mon, 26 Nov 2018 11:06:29 +0100	[thread overview]
Message-ID: <20181126100629.10856-1-s.hauer@pengutronix.de> (raw)

From: Leif Middelschulte <leif.middelschulte@klsmartin.com>

The volume id can be used to refer to a specific volume.
This adds support to choose a corresponding argument when creating
a UBI volume.
