Subject: [PATCH v2 43/46] mtd: nandsim: Wire up NANDSIM_IOC_NEW_INSTANCE
Date: Wed, 21 Sep 2016 11:57:17 +0200	[thread overview]
Message-ID: <7c19d07912a8c93d2ea7fd9c7e3b08d704241b3c.1474450296.git.dwalter@sigma-star.at> (raw)
In-Reply-To: <cover.1474450295.git.dwalter@sigma-star.at>

From: Richard Weinberger <richard@nod.at>

Since we have now all what we need we can arm NANDSIM_IOC_NEW_INSTANCE.
